At the present time, restrictive laws are in force in the United States and it is very difficult for researchers to abide by the regulations which govern efforts to obtain legal approval to do work with these compounds in human beings.... No one who is lacking legal authorization should attempt the synthesis of any of the compounds described in these files, with the intent to give them to man. To do so is to risk legal action which might lead to the tragic ruination of a life. It should also be noted that any person anywhere who experiments on himself, or on another human being, with any of the drugs described herin, without being familiar with that drug's action and aware of the physical and/or mental disturbance or harm it might cause, is acting irresponsibly and immorally, whether or not he is doing so within the bounds of the law. #30 2C-G-5; 3,6-DIMETHOXY-4-(2-AMINOETHYL)BENZONORBORNANE SYNTHESIS: To a stirred solution of 25 g 3,6-dihydroxybenzonorbornane (from Eastman Kodak Company) in 200 mL acetone there was added 200 mg decyltriethylammonium iodide, 40 g of powdered anhydrous K2CO3, and 55 g methyl iodide. The mixture was held at reflux with a heating mantle overnight. After re-moval of the solvent under vacuum, the residue was added to 2 L of H2O, acidified with concentrated HCl, and extracted with 3x100 mL CH2Cl2. The pooled extracts were washed with 2x150 mL 5% NaOH and once with dilute HCl, and the solvent was removed under vacuum to give 19.0 g of a black oil as a residue. This was distilled at 90-115 !C at 0.3 mm/Hg to yield 15.5 g of an orange oil which set up as a crystalline solid. The product, 3,6-dimethoxybenzonorbornane, had a mp of 35-37 !C from hexane or 40-41 !C from MeOH. Anal. (C13H16O2) C,H. A solution of 4.6 g POCl3 and 4.6 g N-methylformanilide was heated briefly on the steam-bath until the color had become deep claret. There was then added 3.05 g of 3,6-dimethoxybenzonorbornane and the solution was heated on the steam bath for 12 h. The black, tarry reaction mixture was poured into H2O, and after hydrolysis, the H2O was decanted and the insoluble residues were washed alternately with H2O and with CH2Cl2. The combined washes were separated, and the aqueous phase extracted with 2x50 mL CH2Cl2. The combined organic fractions were washed with 5% NaOH, and the solvent removed under vacuum. The fluid, black residue was distilled at 130-140 !C at 0.3 mm/Hg to give 1.17 g of an almost white oil. This was dissolved in 1 mL MeOH, and cooled to -50 !C to give a white crystalline solid that was removed by filtration and washed sparingly with -50 !C MeOH and air dried. There was obtained 0.83 g 3,6-dimethoxy-4-formylbenzonorbornane with a mp of 37-40 !C which could be increased, by wasteful recrystallization from MeOH, to 53-54 !C. An intimate mixture of this product with the starting diether (mp 40-41 !C) was a liquid at room temperature. Anal. (C14H16O3) C,H. To a solution of 3.70 g 3,6-dimethoxy-4-formylbenzonorbornane in 20 g nitromethane, there was added 1.3 g anhydrous ammonium acetate and the mixture was heated on the steam bath for 45 min. The excess reagent/solvent was removed under vacuum, and the residue was dissolved in 20 mL boiling MeOH. A speck of seed crystal started a heavy crystallization of orange crystals which were removed by filtration and washed with MeOH. After drying, the product 3,6-dimethoxy-4-(2-nitrovinyl)benzonorbornane was yellow, weighed 3.47 g, and had a mp of 88-89 !C. Recrystallization of an analytical sample from MeOH did not improve this mp. Anal. (C15H17NO4) C,H. A solution of LAH (46 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 1.25 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 3.4 g 3,6-dimethoxy-4-(2-nitrovinyl)benzonorbornane in 30 mL anhydrous THF. After a few min further stirring, the temperature was brought up to a gentle reflux on the steam bath for 10 min, and then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of 7 mL IPA, followed by 2 mL 15% NaOH and 5 mL H2O, which gave an easily filtered white granular solid. This was removed by filtration, and the filter cake was washed with THF. The combined filtrate and washes were stripped of solvent under vacuum providing a pale amber oil which was distilled at 150-160 !C at 0.3 mm/Hg to give 1.45 g of a white oil. This was dissolved in 7 mL IPA, and neutralized with 15 drops of concentrated HCl. There was then added 25 mL anhydrous Et2O and, after a short delay, white crystals formed spontaneously. These were removed by filtration, Et2O washed, and air dried to constant weight, yielding 1.13 g of 3,6-dimethoxy-4-(2-aminoethyl)benzonorbornane hydrochloride (2C-G-5). The mp was 199-200 !C. Anal. (C15H22ClNO2) C,H. DOSAGE: 10 - 16 mg. DURATION: 32 - 48 h. QUALITATIVE COMMENTS: (with 14 mg) I was well aware of things at the end of two hours, and I was totally unwilling to drive, or even go out of the house. I was reminded continuously of 2C-B with its erotic push, and the benign interplay of colors and other visual effects. But it is so much longer lived. I am a full +++, very stoned, and there is no believable sign of dropping for another several hours. There is a good appetite (again, 2C-B like), and I managed to sleep for a few hours, and all the next day I was spacey and probably still a plus one. The day yet following, I was finally at a believable baseline. Both of these days were filled with what might be called micro doze-offs, almost like narcolepsy. Maybe I am just sleep deprived. (with 16 mg) The first effects were felt within one hour, and full effects between 2 1/2 and 3 hours. Tremendous clarity of thought, cosmic but grounded, as it were. This is not at all like LSD, and is a lot mellower than the 2C-T family. For the next few hours it was delightful and fun and I felt safe and good-humored. I got to sleep without much difficulty while still at a plus three, and my dreams were positive and balanced, but I awoke irritable and emotionally flattened. I did not want to interact with anyone. The first 16 hours of this stuff were great, and the second 16 hours were a bit of a drag. Just twice as long as it ought to be. (with 16 mg) I was at full sparkle within three hours, and I continued to sparkle for the longest time. The tiredness that comes after a while probably reflects the inadequacy of sleep. I was aware of something still going on some two days later. EXTENSIONS AND COMMENTARY: In the eventual potency assessment of a drug, there must be some consideration of not only the dosage needed, but the duration of effects. The area under the curve, so to speak. By these measures, this phenethylamine is a record breaker, in that it is not only amongst the most potent, but it goes on and on and on. There are a couple of chemical commentaries. One, the miserable phenol-to-ether-to-aldehyde series of steps, so maddeningly unsatisfactory in the 2C-G-4 process, was completely comfortable here. The reactions rolled, and the yields were most satisfactory. Secondly, this is one of the few phenethylamines that is a racemate. The strange geometry of the norbornane ring carries within it a chiral character, so this compound is potentially resolvable into two optically active forms. That might be quite a task, but it would have the value of providing for the first time a pair of isomers that were asymmetric in the 3,4-aliphatic part of the molecule. To the extent that some insight into the geometry of the receptor site can be gleaned from the absolute configurations of active agonists, here is a compound where the subtle variations are over there at the ring substitution area of the structure, rather than at the well-explored alpha-carbon atom. Some day I might try to resolve this drug into its optical isomers. But I suspect that it might be quite difficult. A number of chemical variations of 2C-G-5 are obvious. The dihydroxybenzonorbornane compound that was the starting point of all this was certainly the adduct of cyclopentadiene and benzoquinone, with the double bond reduced. The same chemistry with 1,3-cyclohexadiene would give a two-carbon bridge instead of the one-carbon bridge of norbornane and, after hydrogenation, would provide a non-chiral analog with two ethylene bridges between the 3- and 4-position carbons. This is a cyclohexane ring connected, by its 1- and 4-positions, to the two methyl groups of 2C-G. With six carbons in this aliphatic mess, the compound is probably best called 2C-G-6. It should be easily made, and it is certain to be very potent. And there are potentially several other Diels Alder dienes that might serve with benzoquinone as the dieneophile. There are aliphatic things such as hexa-2,4-diene and 2,3-dimethylbutadiene. The textbooks are filled with dozens of diene candidates, and benzquinone will always provide the two oxygens needed for the eventual 2,5-dimethoxy groups of the phenethylamine. #31 2C-G-N; 1,4-DIMETHOXYNAPHTHYL-2-ETHYLAMINE SYNTHESIS: A solution of 17.5 g 1,4-naphthaquinone in 200 mL MeOH was heated to the boiling point, and treated with 28.5 g stannous chloride at a rate that maintained a continuous rolling boil. At the completion of the addition, the reaction mixture was saturated with anhydrous hydrogen chloride, and held at reflux on the steam bath for 2 h. The reaction mixture was poured into 700 mL H2O and treated with aqueous NaOH. During the addition there was transient development of a curdy white solid which redissolved when the system became strongly basic. This was extracted with 3x200 mL CH2Cl2 and the pooled extracts were washed first with H2O, then with dilute HCl, and finally again with H2O. Removal of the solvent under vacuum yielded 15.75 g of a low melting black flaky crystalline material which was distilled at 160-180 !C at 0.05 mm/Hg to give 14.5 g of an amber, solid mass with a mp of 78-86 !C. Recrystallization from 75 mL boiling MeOH provided 1,4-dimethoxynaphthalene as white crystals melting at 87-88 !C. A mixture of 20.0 g POCl3 and 22.5 g N-methylformanilide was allowed to stand at room temperature for 0.5 h which produced a deep claret color. To this there was added 9.4 g 1,4-dimethoxynaphthalene and the mixture was heated on the steam bath. The reaction mixture quickly became progressively darker and thicker. After 20 min it was poured into 250 mL H2O and stirred for several h. The solids were removed by filtration, and washed well with H2O. The wet crude product (a dull yellow-orange color) was dissolved in 125 mL boiling EtOH to give a deep red solution. On cooling, this deposited a heavy crop of crystals that was removed by filtration, and washed with cold EtOH. There was obtained, after air-drying to constant weight, 7.9 g 1,4-dimethoxy-2-naphthaldehyde as white crystals with a mp of 119-121 !C. This was not improved by further recrystallization. The malononitrile derivative, from the aldehyde and malononitrile in EtOH with a drop of triethylamine, had a mp of 187-188 !C. A solution of 3.9 g 1,4-dimethoxy-2-naphthaldehyde in 13.5 g nitromethane was treated with 0.7 g anhydrous ammonium acetate, and heated on the steam bath for 1 h. The excess reagent/solvent was removed under vacuum giving a residue that spontaneously crystallized. This crude product was removed with the aid of a few mL MeOH, and pressed on a sintered funnel with modest MeOH washing. There was obtained 3.6 g (when dry) of old-gold colored crystals with a mp of 146-148 !C. Recrystallization from 140 mL boiling EtOH gave 3.0 g 1,4-dimethoxy-2-(2-nitro-vinyl)naphthalene as deep gold-colored crystals with a mp of 146-147 !C. A small sample, upon recrystalization from MeOH, melted at 143-144 !C. Anal. (C14H13NO4) C,H. A solution of LAH (50 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 1.32 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 2.80 g 1,4-dimethoxy-2-(2-nitrovinyl)naphthalene in 40 mL anhydrous THF. There was an immediate loss of color. After 1 h stirring at 0 !C, the temperature was brought up to a gentle reflux on the steam bath for 20 min, then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of 7 mL IPA followed by 5.5 mL 5% NaOH. The reaction mixture was filtered, and the filter cake washed with several portions of THF. The combined filtrate and washings were stripped of solvent under vacuum providing 3.6 g of a pale amber oil that was distilled at 145-160 !C at 0.2 mm/Hg to give 1.25 g of product as an absolutely white oil. This was dissolved in 7 mL IPA, and neutralized with concentrated HCl forming immediate crystals of the hydrochloride salt in the alcohol solvent. Thirty mL of anhydrous Et2O was added, and after complete grinding and mixing, the hydrochloride salt was removed by filtration, Et2O washed, and air dried to constant weight. The spectacular white crystals of 1,4-dimethoxynaphthyl-2-ethylamine hydrochloride (2C-G-N) weighed 1.23 g and had melting properties of darkening at 190 !C, and decomposing in the 235-245 !C area. Anal. (C14H18ClNO2) C,H. DOSAGE: 20 - 40 mg. DURATION: 20 - 30 h. QUALITATIVE COMMENTS: (with 24 mg) The effects were interestingly colored by the reading of Alan WattsU Joyous Cosmology during the coming-on period. The only body negatives were some urinary retention and a feeling of a shallow but continuing amphetamine stimulation. But not enough to be actually jingly, nor to interfere with sleep that evening. There is not much psychedelic here, but there is something really going on anyway. This has some similarities to the antidepressant world. (with 35 mg) Much writing, much talking, and there was considerable residual awareness the next day. Somehow this material is not as friendly as the other 2C-GUs. (with 35 mg) Thinking is clear. No fuzziness, no feeling of being pushed. None of the walking on the fine middle line between light and dark that is the excitement and the threat of LSD. This is just a friend, an ally, which invites you to do anything you wish to. [comment added two days later] RMy sleep was not deep enough, but it was pleasant and relatively resting. The whole next day I was feeling happy, but with an overlay of irritability. Strange mixture. By bedtime the irritability had become a mild depression. I feel that there might have been a threshold continuing for a couple of days. The character of my dreaming had the stamp of drug on it. This compound, in retrospect, presents some problems that cause a faint unease. EXTENSIONS AND COMMENTARY: There is always a wish in the design of new compounds to find something that is of interesting activity, with an aromatic ring at some location pretty much away from the site of activity. This would then allow some subtle fine-tuning of the nature of the action by putting any of a wide range of electron pushing or electron pulling groups on that ring. But here, with 2C-G-N, by the time the ring got put into place, the activity was already on the wane, and the action was too long, and there are indicators of some not completely friendly effects. Ah well, some other molecule, some other time. #32 2C-H; 2,5-DIMETHOXYPHENETHYLAMINE SYNTHESIS: A solution of 50 g 2,5-dimethoxybenzaldehyde in 100 g nitromethane was treated with 5 g of anhydrous ammonium acetate, and heated on the steam bath for 4 h. The solution was decanted from a little insoluble material, and the solvent removed under vacuum. The clear oily residue was dissolved in 100 mL boiling IPA which, after standing a moment, set up as dense crystals. After returning to room temperature, these were removed by filtration, the product was washed with IPA and air dried, yielding 56.9 g 2,5-dimethoxy-'-nitrostyrene as spectacular yum-yum orange crystals with a mp of 119-120 !C. An analytical sample, from ethyl acetate, melted at 120-121 !C. A suspension of 60 g LAH in 500 mL anhydrous THF was placed under an inert atmosphere, stirred magnetically, and brought up to reflux temperature. There was added, dropwise, 56 g of 2,5-dimethoxy-'-nitrostyrene dissolved in THF, and the reaction mixture was maintained at reflux for 36 h. After being brought to room tem-perature, the excess hydride was destroyed with 40 mL IPA, followed by 50 mL of 15% NaOH. An additional 100 mL THF was required for easy stirring, and an additional 150 mL H2O was needed for complete conversion of the aluminum salts to a loose, white, filterable consistency. This solid was removed by filtration, and the filter cake washed with additional THF. The combined filtrate and washes were stripped of solvent under vacuum, and the residue dissolved in dilute H2SO4. Washing with 3x75 mL CH2Cl2 removed most of the color, and the aqueous phase was made basic with aqueous NaOH and reextracted with 3x100 mL CH2Cl2. Removal of the solvent yielded 39.2 g of a pale amber oil that was distilled. The fraction boiling at 80-100 !C at 0.4 mm/Hg weighed 24.8 g and was water-white product amine. As the free base, it was suitable for most of the further synthetic steps that might be wanted, but in this form it picked up carbon dioxide rapidly when exposed to the air. It was readily converted to the hydrochloride salt by dissolution in 6 volumes of IPA, neutralization with concentrated HCl, and addition of sufficient anhydrous Et2O to produce a permanent turbidity. Crystals of 2,5-dimethoxyphenethylamine hydrochloride (2C-H) spontaneously formed and were removed by filtration, washed with Et2O, and air dried. The mp was 138-139 !C. DOSAGE: unknown. DURATION: unknown. EXTENSIONS AND COMMENTARY: I know of no record of 2C-H ever having been tried by man. It has been assumed by everyone (and probably correctly so) that this amine, being an excellent substrate for the amino oxidase systems in man, will be completely destroyed by the body as soon as it gets into it, and thus be without action. In virtually all animal assays where it has been compared with known psychoactive drugs, it remains at the Rless-activeS end of the ranking. It is, however, one of the most magnificent launching pads for a number of rather unusual and, in a couple of cases, extraordinary drugs. In the lingo of the chemist, it is amenable to Relectrophilic attack at the 4-position.S And, in the lingo of the psychopharmacologist, the R4-position is where the action is.S From this (presumably) inactive thing have evolved end products such as 2C-B, 2C-I, 2C-C, and 2C-N. And in the future, many possible things as might come from a carbinol group, an amine function, or anything that can stem from a lithium atom. #33 2C-I; 2,5-DIMETHOXY-4-IODOPHENETHYLAMINE SYNTHESIS: A mixture of 7.4 g phthalic anhydride and 9.05 g of 2,5-dimethoxyphenethylamine (see the recipe for 2C-H for its preparation) was heated with an open flame. A single clear phase was formed with the loss of H2O. After the hot melt remained quiet for a few moments, it was poured out into a crystallizing dish yielding 14.8 g of a crude solid product. This was recrystallized from 20 mL CH3CN, with care taken for an endothermic dissolution, and an exothermic crystallization. Both transitions must be done without haste. After filtration, the solids were washed with 2x20 mL hexane and air dried to constant weight. A yield of 12.93 g of N-(2-(2,5-dimethoxyphenyl)ethyl)phthalimide was obtained as electrostatic yellow crystals, with a mp of 109-111 !C. A sample recrystallized from IPA was white, with a mp of 110-111 !C. Anal. (C18H17NO4) C,H,N. To a solution of 12.9 g N-(2-(2,5-dimethoxyphenyl)ethyl)phthalimide in 130 mL warm (35 !C) acetic acid which was being vigorously stirred, there was added a solution of 10 g iodine monochloride in 40 mL acetic acid. This was stirred for 1 h, while being held at about 30 !C. The reaction mixture was poured into 1500 mL H2O and extracted with 4x75 mL CH2Cl2. The extracts were pooled, washed once with 150 mL H2O containing 2.0 g sodium dithionite, and the solvent removed under vacuum to give 16.2 g of N-(2-(2,5-dimethoxy-4-iodophenyl)ethyl)phthalimide as yellow amber solids with a mp of 133-141 !C. This mp was improved by recrystallization from 75 mL CH3CN, yielding 12.2 g of a pale yellow solid with mp 149-151 !C. A small sample from a large quantity of IPA gives a white product melting at 155.5-157 !C. A solution of 12.2 g N-(2-(2,5-dimethoxy-4-iodophenyl)ethyl)phthalimide in 150 mL hot IPA was treated with 6.0 mL of hydrazine hydrate, and the clear solution was heated on the steam bath. After a few minutes there was the generation of a white cottage cheese-like solid (1,4-dihydroxyphthalizine). The heating was continued for several additional h, the reaction mixture cooled, and the solids removed by filtration. These were washed with 2x10 mL EtOH, and the pooled filtrate and washes stripped of solvent under vacuum giving a residue which, when treated with aqueous hydrochloric acid, gave 3.43 g of voluminous white crystals. This, after recrystallization from 2 weights of H2O, filtering, washing first with IPA and then with Et2O, and air drying, gave 2.16 g 2,5-dimethoxy-4-iodophenethylamine hydrochloride (2C-I) as a white microcrystalline solid, with a mp of 246-247 !C. Anal. (C10H15ClINO2) C,H,N. DOSAGE: 14 - 22 mg. DURATION: 6 - 10 h. QUALITATIVE COMMENTS (with 0 mg) I was present at a group meeting, but was only an observer. With zero milligrams of 2C-I, I was able to get to a delightful plus 2.5 in about five minutes after I arrived at your place, and absorbed the ambience of the folks who had actually imbibed the material. My level lasted about four hours and came down at about the same time as did the others. There were no after-effects experienced except for a pleasant languor. (with 15 mg) Comfortable onset. Most notable are the visuals, patterning like 2C-B (Persian carpet type), very colorful and active. Much more balanced emotional character, but still no feeling of insight, revelation, or progress toward the true meaning of the universe. And at 5 1/2 hours drop-off very abrupt, then gentle decline. I would like to investigate museum levels. (with 16 mg) There was an immediate alert within minutes. As usual, it was only an awareness, then nothing happened for a while. In retrospect, I see some type of activity or awareness within 40 minutes, which then builds up over time. The peak was at 2 hours and seemed to maintain itself for a while. Near the peak, there was some hallucinogenic activity, though not a lot. The pictures in the dining room had color and pattern movement that was fairly detailed. Focusing on other areas, such as walls or the outside of the house, produced little activity, though I tried. There was certainly a lot of color enhancement. There was also that peculiar aspect of the visual field having darkened or shadowed areas. These darker areas seemed to shift around to some degree. That aspect seems to be similar to 2C-B. I donUt think I was more than +2.5 at the peak. Coming down was uneventful. I was down within 6 hours. I had no problems driving home, nor were there any difficulties with sleep. There were no body problems with this material. I ate like a horse. (with 16 mg) The 16 was a bit much, I realized, because my body was not sure of what to do with all the energy. Next time IUll try 14 or 15. However, my conversations were extremely clear and insightful. The degree of honesty was incredible. I was not afraid to say anything to anyone. Felt really good about myself. Very centered, in fact. A bit tired at day's end. Early bedtime. (with 20 mg) I think there is slightly less than full immersion in the sensual, with this material, compared with 2C-B, but I suspect it's more a matter of getting used to the language of 2C-I and the feelings Q getting tuned to a slightly different frequency, really Q rather than that the material is less sensual or less easy to use sensually. Just different frequency, and we are very, very used to 2C-B. Good on the body. Transition, for me, not as strongly dark as 2C-B. But it could certainly take a lot more exploring, if we were able to give the time (about 9 hours) to it. Next day: sleep excellent. Energy next day unusually good. Quite tired by evening. EXTENSIONS AND COMMENTARY: The frequent comparisons between 2C-I and 2C-B stem, without doubt, from a bit of chemical suggestion. The two compounds have structures that are truly analogous, in technical terms. In one, there is a strategically located iodine atom, and in the other, an identically placed bromine atom. These are directly above and below one-another in the periodic table. And what is particularly maddening to the synthetic diddler, is that they cannot be lengthened, or shortened, or squooshed around in any way. You canUt make a longer and narrower version of a bromine atom, as you can do with, say, a butyl group. YouUve got what youUve got, like it or not. No subtle variations. But, on the brighter side of the picture, you have a heavy atom here, and this atom is intrinsic to the central activity of the compound. So, these materials are naturals for radio-labelling experiments. 2C-I has been made radioactive with radio-iodine, but the most impressive findings have been made with the 3-carbon analog, DOI. One quotation from an observer of a group experiment is enclosed; an experiment with zero milligrams being taken. This is a instructive observation of what has been called a Rcontact high. There is one Iodotweetio known. In Scrabble, would you challenge a word that had seven of its eleven letters as vowels? Especially if the vowels were, specifically, iooeeio? It sounds just a little like the noise coming out of Old McDonald's farm. But a Tweetio there is, namely, the 2-EtO-homologue of 2C-I. This is 2-ethoxy-4-iodo-5-methoxyphenethylamine, or 2CI-2ETO. The hydrochloride salt was a white, crystalline product with a melting point of 175-175.5 !C. The threshold level of activity was seen at an oral dose of 5 milligrams, and the generated effects were completely dispersed in a couple of hours. Most interestingly, larger doses, of up to 50 milligrams orally, seem to produce no more intense an effect, but simply to stretch out this threshold for an additional couple of hours. At no level that has been tried, has 2CI-2EtO produced even a plus-two response. Where else can one go, from 2C-I? The iodine is the fourth, and the last of the so-called halogens, at the bottom of the classical periodic table. But, thanks to the miracles that have accompanied us into the nuclear age, there is a fifth halide now known, Astatine. All of its isotopes are radioactive, however, and it seems unlikely that there will ever be an entry (other than this one) for 2,5-dimethoxy-4-astatophenethylamine. What might be speculated as to its activity? Probably similar in potency to 2C-I, requiring maybe 10 or 20 milligrams. The duration would be dicey to measure, since the isotope with the longest known half-life is half decayed in about 8 hours, and the longest lived natural isotope (for those who insist on natural rather than man-made things) is half decayed in less than a minute. Two predictions would be pretty solid. You might have quite a job accumulating your 10 milligrams of Astatine, as the most that has so far been made at one time is only about 0.05 micrograms, approximately a millionth of the amount needed. And the second prediction? You would not survive the screaming radiation that would bombard you if you could get the needed 5 or 10 milligrams of radio-astatine onto that magic 4-position, and the resulting 2C-A into your tummy! #34 2C-N; 2,5-DIMETHOXY-4-NITROPHENETHYLAMINE SYNTHESIS: A cooled, stirred solution of 1.0 g 2,5-dimethoxyphenethylamine (see the recipe for 2C-H for its preparation) in 20 mL glacial acetic acid was treated with 3.3 mL 70% HNO3 in small portions, with the reaction temperature kept down with periodic cooling. After the addition was completed, the stirring was continued until there was the spontaneous separation of a yellow solid. This was 2,5-dimethoxy-4-nitrophenethylamine nitrate (2C-N) which was obtained after removal by filtration, washing with Et2O and air drying, as a fluffy yellow solid. This weighed 1.04 g and melted, with decomposition, in the area of 170-180 !C, depending on the rate of heating. A solution of 0.8 g of this nitrate salt in 50 mL H2O was made basic with aqueous NaOH. Extraction with 3x50 mL CH2Cl2, and removal of the solvent under vacuum gave the free base as a residue. This was distilled at 130-150 !C at 0.35 mm/Hg to give an orange-red oil that weighed 0.5 g and set up as crystals. This was dissolved in 3 mL IPA, neutralized with 7 drops of concentrated HCl (the color lightened considerably at the titration end point) and diluted with 5 mL anhydrous Et2O. There was the formation of the hydrochloride salt which was a pumpkin-colored crystalline mass. After removal by filtration, Et2O washing and air drying, these crystals weighed 0.44 g. The mp, 193-195 !C, was not improved by recrystallization from any of several solvents (MeOH, IPA, CH3CN). The perchlorate salt was a yellow solid from MeOH, with a mp of 211 !C, with decomposition. Nitration of 2C-H in a mixture of acetic acid and acetic anhydride produced the acetamide derivative of 2C-N as yellow crystals with a mp 142.5-143 !C. For the nitrate salt: Anal. (C10H15N3O7) C,H. This was the form used for all human titrations. DOSAGE: 100 - 150 mg. DURATION: 4 - 6 h. QUALITATIVE COMMENTS: (with 120 mg) This came on very fast Q I was aware of it within a half hour, and it got as far as it would go by an hour. There are similarities to MDMA, but missing is the benign anti-stress component. I am light-headed, and there just might be a little eye wiggling. And then it dropped right off to nothing within a couple of hours. (with 150 mg) There may have been some visual changes, IUm not sure. But the talking was extremely easy. If there were no other things to use, this would be excellent, but there are other compounds available. This doesnUt have too high a priority. (with 150 mg) Am I enjoying it? Not exactly, but I am in a good mood. There is not the light-filled energy that some other materials can provide. By six hours, pretty much baseline. Strange material, but okay. Final score: body +3, mind +2, barely. EXTENSIONS AND COMMENTARY: A most consistent feature with 2C-N was the fact that in every report, somewhere, there is the note that it somehow came up just a little short of expectations. From the esthetic point of view, the pure salt is yellow rather than the usual white color, so the solutions that are to be consumed are by definition also yellow colored. From the structural point of view, the 4-nitro group, like the 4-bromo group of 2C-B, is a dead-end. It cannot be stretched or compressed or lengthened or shortened. This unique aspect demands that you have to live with what you have, as there are no subtle ways of modifying the molecule. With 2C-B, the end product was a total winner; there was no wish to modify it. With 2C-N the end product is something a little less, and there is no way to modify it. #35 2C-O-4; 2,5-DIMETHOXY-4-(i)-PROPOXYPHENETHYLAMINE SYNTHESIS: To a solution of 3.10 g 85% KOH pellets in 30 mL warm MeOH there was added 6.16 g 2,5-dimethoxyphenol (there was immediate darkening) followed by 8.5 g isopropyl iodide. The reaction mixture was heated on the steam bath for 3.5 h. White crystals of KI appeared at the end of the first h. The mixture was poured into 800 mL H2O (it was still basic) and acidified with HCl. This was extracted with 3x100 mL CH2Cl2, and the combined extracts washed with 2x100 mL 5% NaOH. The organic phase was stripped of solvent under vacuum, and the residual dark amber oil (6.4 g) distilled at 110-130 !C at 0.7 mm/Hg. There was obtained 5.7 g of 1,4-dimethoxy-2-(i)-propoxybenzene as a white oil. A mixture of 10 g N-methylformanilide and 10 g POCl3 was heated on the steam bath for 10 min producing a deep claret color. To this there was added 5.1 g of 1,4-dimethoxy-2-(i)-propoxybenzene, and the immediately exothermic reaction mixture was heated on the steam bath for 45 min. It was then poured into 800 mL H2O which was stirred until the dark oil changed into loose, light-colored solids. These were removed by filtration giving 5.7 g of an amber crystalline product with a mp of 76-78 !C. This was dissolved in an equal weight of MeOH, and heated to a solution which was clear at the boiling point. This was brought to 0 !C and held there for several hours, yielding 2,5-dimethoxy-4-(i)-propoxybenzaldehyde as a fine, off-white crystalline product which, after filtering and air drying, weighed 4.03 g. The mp was 79-80 !C with prior shrinking at 71 !C. Anal. (C12H16O4) C,H. A solution of 3.9 g 2,5-dimethoxy-4-(i)-propoxybenzaldehyde in 20 g nitromethane was treated with 0.17 g anhydrous ammonium acetate and heated on the steam bath for 1.25 h. The progress of the condensation was readily followed by a TLC analysis of the reaction mixture. With silica gel plates, the starting aldehyde and the product nitrostyrene had Rf's of 0.16 and 0.50 resp., using CH2Cl2 as a developing solvent. The excess solvent was removed under vacuum to give a red residue that was dissolved in 10 mL boiling MeOH. The solution spontaneously crystallized giving, after filteration and air drying, 4.1 g of orange crystals of 2,5-dimethoxy-'-nitro-4-(i)-propoxystyrene. A solution of LAH (60 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 1.60 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 4.0 g 2,5-dimethoxy-'-nitro-4-(i)-propoxystyrene as a solid, perhaps 200 mg at a time. There was an immediate loss of color after each addition. The final pale salmon-colored solution was stirred for 2 h as it returned to room temperature. The excess hydride was destroyed by the cautious addition of 8 mL IPA, which was followed by 5 mL 15% NaOH followed, in turn, by sufficient additional THF to make the suspension of inorganic salts loose and filterable. The reaction mixture was filtered, and the filter cake washed with additional THF. The filtrate and washings were combined and stripped of solvent under vacuum providing 4.6 g of a pale amber oil. This was dissolved in dilute H2SO4, washed with 2x50 mL CH2Cl2, made basic with aqueous NaOH, and extracted with 3x50 mL CH2Cl2. Removal of the solvent under vacuum yielded 2.3 g of residue which was distilled at 115-125 !C at 0.3 mm/Hg to give 0.94 g of a clear white oil. This was dissolved in 5 mL IPA, neutralized with 12 drops of concentrated HCl, and diluted with 10 mL anhydrous Et2O. White crystals of 2,5-dimethoxy-4-(i)-propoxyphenethylamine hydrochloride (2C-O-4) separated, and were removed by filtration, Et2O washed, and air dried. The final weight was 0.58 g. DOSAGE: greater than 60 mg. DURATION: unknown QUALITATIVE COMMENTS: (with 60 mg) I became aware of something in the front part of my head, and there was a lot of yawning. The body was aware of the experiment. But also there was a general exhilaration and excitement, which lasted for a few hours. At best, I am at a plus one. EXTENSIONS AND COMMENTARY: The full activity of 2C-O-4 is yet to be discovered. It represents an interesting hybrid lying in between several fascinating compounds. First and foremost, all these carry the 2,4,5-trisubstitution which has consistently proven to be the most interesting and the most active of the phenethylamines. And with very few exceptions, the 2- and the 5- are methoxyl groups. The sulfur analogues in this area, compounds with an alkylthio group at the 4-position of the 2,5-dimethoxyphenethylamine backbone, are the 2C-T things. The replacement of a sulfur with an oxygen, quite rightly, should give rise to the 2C-O counterparts. And they have been given the same numbering system that was bestowed upon the RTS series. 2C-T-4 was the 4-isopropylthio compound and one of the most interesting of this family. And so, quite reasonably, the oxygen coun-terpart should be the 2C-O-4 analogue, and should be one of the first explored. The extension of the 4-alkoxy-group led to the discovery of the TMA-2 Q MEM Q MIPM Q MPM Q MBM series of amphetamine analogues. The 2-carbon counterparts of these would be a fascinating series to explore, I thought, if there was some encouragement to be had from a preliminary try in this field. This was a first shot in the dark, the actual trial example, and it certainly didnUt provide much encouragement. The three-carbon analogue, MIPM, was made (q.v.) but not explored, following the disappointing trials of MPM. If this area is ever re-opened, the numbering should reasonably follow the sulfur materials. The 4-ethoxy material would be 2C-O-2, the 4-(n)-propoxy compound 2C-O-7, and the 4-(n)-butoxy compound 2C-O-19. These are the exact analogues of 2C-T-2, 2C-T-7, and 2C-T-19, resp., and the 2-carbon homologues of MEM, MPM, and MBM. The simplest member of this series, the methyl counterpart, is 2C-O, and it is the obvious analogue of 2C-T. This is also called 2,4,5-TMPEA, and its story is presented elsewhere. But, with the probable low eventual potency of 2C-O-4, I feel that the 2C-O series will not be an exciting one. #36 2C-P; 2,5-DIMETHOXY-4-(n)-PROPYLPHENETHYLAMINE SYNTHESIS: To a stirred solution of 138 g p-dimethoxybenzene in 400 mL CH2Cl2 there was added a suspension of 172 g anhydrous AlCl3 in 500 mL CH2Cl2 which contained 92.5 g propionyl chloride. After stirring for 1.5 h the reaction mixture was poured into 2 L H2O containing ice. The phases were separated, and the aqueous fraction was extracted with 2x100 mL CH2Cl2. The organic phase and the extracts were pooled, washed once with H2O, and then with 2x100 mL 5% NaOH. The solvent from the organic phase was removed under vacuum, yielding a deeply colored residue. This was distilled at 150-165 !C at 20 mm/Hg yielding 170 g of 2,5-dimethoxypropiophenone as a pale amber-colored oil. Acidification of the sodium hydroxide extract, extraction with CH2Cl2, and evaporation of the solvent, yielded 3 g of an oil that slowly crystallized. These solids, on recrystallization from MeOH, provided 1.0 g of 2-hydroxy-5-methoxypropiophenone with a mp of 47-48 !C. The same Friedel Crafts reaction, conducted on the same scale in CS2 rather than in CH2Cl2, required reduced temperature (5 !C) and a 24 h reaction period. This solvent variation, with the same workup and isolation, gave 76 g of 2,5-dimethoxypropiophenone as a pale amber oil boiling at 130-137 !C at 4 mm/Hg. A total of 150 g mossy zinc was amalgamated by treatment with a solution of 15 g mercuric chloride in 1 L H2O. After swirling for 0.5 h, the H2O phase was removed by decantation and the zinc added to a 1 L three neck flask. To this there was added 20 mL H2O and 20 mL concentrated HCl, followed by 20 g of 2,5-di-methoxypropiophenone dissolved in 50 mL EtOH. This mixture was held at reflux with a heating mantle overnight, with the occasional addition of HCl as needed to maintain acidic conditions. After cooling to room temperature, the residual solids were removed by filtration, and the filtrate extracted once with 100 mL CH2Cl2 (this was the upper phase). Sufficient H2O was then added to allow extraction with 2x100 mL additional CH2Cl2 with the organic solvent being the lower phase. The combined organic extracts were washed twice with 5% NaOH, followed by one washing with dilute acid. Removal of the solvent under vacuum yielded 18 g of a dark brown oil that was distilled at the water pump to yield 7.2 g of 2,5-dimethoxypropylbenzene as a light yellow oil boiling at 90-130 !C. A mixture of 22 g 2,5-dimethoxypropylbenzene, 23 g POCl3 and 22 g N-methylformanilide was heated on the steam bath for 1.5 h. The hot, dark reaction mass was poured into 1 L H2O, which allowed the eventual separation of 2,5-dimethoxy-4-(n)-propylbenzaldehyde as a clear yellow oil weighting 14 g. Although the homologous 4-ethyl and 4-butyl benzaldehydes were clean crystalline solids, this propyl homologue remained an oil. Gas chromatographic analysis showed it to be about 90% pure, and it was used as obtained in the nitrostyrene steps with either nitromethane (here) or nitroethane (under DOPR). To a solution of 13 g 2,5-dimethoxy-4-(n)-propylbenzaldehyde in 100 mL nitromethane, there was added 1.3 g anhydrous ammonium acetate and the mixture held at reflux for 1 h. Removal of the solvent/reactant under vacuum yielded a spontaneously crystallizing mass of orange solids that was removed with the help of a little MeOH. After filtering and air drying there was obtained 7.5 g 2,5-dimethoxy-'-nitro-4-(n)-propylstyrene with a mp of 118-122 !C. Recrystallization from CH3CN gave an analytical sample with a mp 123-124 !C. Anal. (C13H17NO4) N. In a 1 L round bottomed flask with a magnetic stirrer under a He atmosphere there was added 120 mL 1 M LAH in tetrahydrofuran. This stirred solution was cooled with an external ice bath, and there was added, dropwise, 3.2 mL of 100% H2SO4, freshly made by the addition of 13.5 g 20% fuming H2SO4 to 15.0 g of ordinary 96% concentrated H2SO4. When the addition was complete, a total of 7.2 g of dry 2,5-dimethoxy-'-nitro-4-(n)-propylstyrene was introduced as solids in several batches, against a flow of He, over the course of 20 min. The reaction mixture was allowed to come to room temperature, and stirred for an additional 0.5 h, then brought to reflux for 10 min on the steam bath. The excess hydride was destroyed with 18 mL IPA, and then sufficient 15% NaOH was added which made the aluminum oxides distinctly basic and of a filterable texture. The inorganics were removed by filtration, and the filter cake washed with additional THF. The combined filrate and washes were stripped of solvent, yielding several g of a pale yellow oil that was suspended in a large quantity of dilute H2SO4. The aqueous phase was filtered free of insolubles, washed with a little CH2Cl2, and made basic with aqueous NaOH. This was extracted with 3x40 mL CH2Cl2 and, after the removal of the solvent under vacuum, the residual 2 g of off-white oil was distilled. A fraction that distilled at 100-110 !C at 0.3 mm/Hg was water white, weighed 1.59 g and spontaneously crystallized. This fraction was dissolved in 7.5 mL warm IPA and neutralized with 0.6 mL concentrated HCl. The spontaneous crystals of 2,5-di-methoxy-4-(n)-propylphenethylamine hydrochloride (2C-P) were suspended in 20 mL anhydrous Et2O, filtered, Et2O washed, and air dried. The weight was 1.65 g and the mp was 207-209 !C with prior sintering at 183 !C., Anal. (C13H22ClNO2) N. DOSAGE: 6 - 10 mg. DURATION: 10 - 16 h. QUALITATIVE COMMENTS: (with 6 mg) I was not feeling so good. Hangover, I guess. The material was so gentle in coming on, and soon my body became jangled. Thinking was easy. Verbalizing was easy. Being comfortable with my body was not. My back hurt and then my legs hurt. My lower back was in spasm. At first I did not particularly like what this drug was doing to my body, but took a good look at it and decided that I was the culprit. Took a good look at my drinking so much, and decided that I didnUt need it. So much energy was going through me I didnUt know what to do with it. The whole day was spent in physical discomfort. Food tasted good, and we nibbled all day. My stomach was bloated. Next day I was more or less like a zombie. I was wiped out. (with 8 mg) Comes on slowly, not feeling intently until into 2nd hour. I feel slight discomfort but override it responding to music. I take in air, directing it inside to heal uncomfortable places, open up my clogged sinuses. Wonderful experience of clean, fresh, healing air. Find that discomfort zone is places where I think there is something wrong with me. I dissolve these places with the feeling IUm OK. Like myself better and better, and find more reasons to enjoy and appreciate myself. I find this material powerful, and an excellent working material. Under other circumstances, would probably spend more time working alone inside, where there were great openings, and some of the most beautiful visuals I have seen for a long time. Usually I do not get visuals. I like the long action. I feel that this material worked for a good week after the experience, with internal processes taking place, many insights, and energy running. At times the energy was a little uncom-fortable, but could always be quelled by taking a moment for deep relaxation or looking directly at the internal process. I feel that much good internal work has been done, a lot of it unconscious. (with 9 mg) At the one hour point, I am barely off of baseline. It is not until almost the third hour that the experience is fully developed, and once there it is maintained for another four hours. I was well grounded but rather diffuse. I explored writing (which went quite well), interpretation (pictures and reading both OK) and talking (very good). This is an excellent level, and probably near the max. (with 12 mg) Slow and even rise. At five minutes to seven (suddenly the clock time makes no sense at all) I am at a 3+ and feel that I have not yet plateauUd. Erotic was excellent. Music good. Eyes-closed imagery very different place than usual experiences. Slow, calm, strong images from an area that has no apparent connection with usual waking world, yet underlies all of it. A cool, wise place which has its own rules. All emotions and feeling available, but there is a cool perspective which informs all thinking. Talking superb and fun, and it was possible to feel our bodies healthy and full of determination to remain so, despite obvious faults and self-indulgences. Could do a lot of learning with this material, but probably not a group thing. It would lend itself too easily to hypnotic power-games, and it would be too easy to open up the shared consciousness level, which would be frightening to a lot of people and bring about necessary escapes such as sickness. Excellent feeling the next day. EXTENSIONS AND COMMENTARY: There is certainly a broad mixture of experiences with 2C-P but, on the whole, probably more favorable than not. There was one report of an experience in which a single dosage of 16 mg was clearly an overdose, with the entire experiment labeled a physical disaster, not to be repeated. A consistent observation is that there may not be too much latitude in dosage between that which would be modest, or adequate, and that which would be excessive. The need for individual titration would be most important with this compound. #37 CPM; CYCLOPROPYLMESCALINE; 4-CYCLOPROPYLMETHOXY-3,5-DIMETHOXYPHENETHYLAMINE SYNTHESIS: To a solution of 2.8 g homosyringonitrile (see under E for synthesis) in 20 ml acetone containing about 50 mg decyltriethylammonium iodide, there was added 3.0 g cyclopropylmethyl chloride and 5.0 g NaI. Stirring was continued during a color change from pale yellow to blue. There was then added 2.9 g of finely powdered anhydrous K2CO3, resulting in a beautiful turquoise color. The mixture was held at reflux on the steam bath for 3 h, which discharged all color. The solvent was removed under vacuum, and the residues were added to 100 mL H2O. This solution was extracted with 3x75 mL CH2Cl2, the extracts were pooled, washed with 2x50 mL 5% NaOH, and the organic solvent removed under vacuum. The residual oil weighed 4.2 g, and was distilled at 140-155 !C at 0.4 mm/Hg to yield 4-cyclopropylmethoxy-3,5-dimethoxyphenylacetonitrile as a colorless oil weighing 2.8 g which spontaneously crystallized. Its mp was 44-44.5 !C after recrystallization from MeOH/H2O. Anal. (C14H17NO3) C,H. A suspension of 1.3 g LAH in 65 mL anhydrous THF under He was cooled to 0 !C with stirring, and 0.85 mL of 100% H2SO4 was slowly added. Then, with continued stirring, a THF solution of 2.7 g of 4-cyclopropylmethoxy-3,5-dimethoxyphenylacetonitrile in 50 mL THF was added dropwise. After the addition was complete, the mixture was brought to a boil briefly on the steam bath, cooled, and treated with sufficient IPA to destroy the excess hydride. Then there was added an amount of 15% NaOH sufficient to produce a loose filterable solid form of aluminum oxide. This was removed by filtration, and the filter cake washed with THF. The pooled filtrate and washes were stripped of solvent, and the residue was dissolved in dilute H2SO4, washed with 2x50 mL CH2Cl2, made basic with aqueous NaOH, and then extracted with 2x50 mL of CH2Cl2. After removal of the solvent, the residue was distilled at 128-140 !C at 0.4 mm/Hg to yield 2.5 g of a white oil. This was dissolved in 10 mL IPA, and treated with 30 drops of concentrated HCl which was just sufficient to demonstrate acidity as judged by external dampened pH paper. The addition of 25 mL anhydrous Et2O to the stirred solution allowed, in a few minutes, the product 4-cyclopropylmethoxy-3,5-dimethoxyphenethylamine hydrochloride (CPM) to spontaneously crystallize as a fine white solid. The yield was 1.8 g, and a second crop of 0.8 g was obtained from the IPA/Et2O mother liquors. The mp was 172-173 !C. Anal. (C14H22ClNO3) C,H. DOSAGE: 60 - 80 mg. DURATION: 12 - 18 h. QUALITATIVE COMMENTS: (with 70 mg) I was surprised at the fast development of this drug, with the knowledge that it was a long-laster. Twenty minutes into it I was aware of some changes, and by the end of one and a half hours there was a complete plus three. The most remarkable property is the eyes-closed imagery. No, not just imagery but fantasy. It is not completely benign, but it locks into music with an extraordinary fit. I was at one moment keenly aware of my body touching the rug, the tactile aspects of my surroundings, and then I would find that my world was simply my personal sphere of reality that kept engulfing everything about me, all completely augmented by the music. Constructed by the music. I hoped that I wouldnUt offend anyone else around me with this growing world of mine. Eyes open, there was not that much of note. Not much insight. Not much in the way of visuals. By the eighth hour an effort to sleep showed me how exposed and vunerable I was, and when I closed my eyes I needed my guards against this fantasy world. Even at the twelth hour there was no easy way to relax and sleep. Use higher dosages with caution. (with 70 mg) There is a goodly amount of eyes-closed patterning but I found external sounds to be irritating. Voices, and even music, seemed to be intrusive. I didnUt want to share my space with anyone. I was reminded of mescaline, in that I kept losing the awareness of the drug's role in my experience. Visual exaggerations are probably right around the corner. The residual effects were too much to ignore, but 100 milligrams of phenobarb at about the twelth hour allowed me to lie down quietly. (with 80 mg) A wild day of profound philosophy, with discussions of the art of molecules, the origins of the universe, and similar weighty trivia. Much day-dreaming in erotic areas, but by and large, it went on a bit too long. I was tired. EXTENSIONS AND COMMENTARY: In the literary world, the guy who is on your side, your leader, your champion, is the protagonist and the guy he battles, your enemy, is the antagonist. These same roles are played in the world of pharmacology, but the names are slightly changed. A drug which does the needed or expected thing is called the agonist rather than protagonist, but the drug that gets in its way is still called the antagonist. The cyclopropylmethyl group plays an interesting role in the world of narcotics. There are numerous examples of opiates with a methyl group attached to a nitrogen atom which are famous for being valuable in producing analgesia and sedation. These run the gamut from natural alkaloids such as morphine and codeine, to synthetic variants such as Dilaudid and Percodan. And yet, with most of these narcotics, when the methyl on the nitrogen is removed, and a cyclopropylmethyl group put into its place, the agonist becomes an antagonist. Oxycodone (the active narcotic thing in Percodan) becomes Naltrexone, a drug that will immediately snap a heroin victim out of his overdose. Cyclopropylmescaline (CPM) is a molecule that is very simply mescaline itself, with a methyl group removed from an oxygen atom and a cyclopropylmethyl group put on instead. Might CPM be not only inactive, but actually block the action of mescaline? Interesting concept. But it turned out to be entirely wrong. The amphetamine analog of CPM should be easily made from the alkyl-ation of syringaldehyde with cyclopropyl chloride, followed by conventional reaction of the resulting aldehyde with nitroethane, and finally a reduction step. There is no reason to believe that the resulting compound 3,5-dimethoxy-4-cyclo-propyloxyamphetamine (3C-CPM) would be any shorter acting than CPM. #38 2C-SE; 2,5-DIMETHOXY-4-METHYLSELENEOPHENETHYLAMINE SYNTHESIS: A suspension of 5.65 g 1,4-dimethoxybenzene in 100 mL petroleum ether containing 6.5 mL N,N,NU,NU-tetramethylethylenediamine was magnetically stirred, placed in an inert atmosphere, and cooled to 0 !C with an external ice bath. There was then added 27 mL of 1.6 M butyllithium in hexane. The solids present went into solution, and after a few min continued stirring, a fine precipitate appeared. The reaction was allowed to stir while coming up to room temperature. There was then added 4.8 g dimethyl diselenide which led to an exothermic reaction, bringing the petroleum ether up to a reflux and showing a color change from white to yellow, to light green, to an eventual brown, all over the course of 30 min. After 2 h additional stirring, the reaction was quenched by pouring into dilute NaOH. The organic phase was separated, and the aqueous phase extracted with 2x75 mL Et2O. The pooled organics were washed first with dilute NaOH, then with dilute HCl, and then the solvent was removed under vacuum. Distillation of the residue at 0.4 mm/Hg gave an early fraction (75-100 !C) that solidified in the receiver and was largely unreacted dimethoxybenzene. A pale yellow oil distilled from 100 to 120 !C which proved to be largely 2,5-dimethoxyphenyl methyl selenide. Microanalysis gave C = 49.86, 49.69; H = 5.32, 5.47. As C9H12SeO2 requires C = 46.76, H = 5.23, there is approximately 13% dimethoxybenzene present (C8H10O2 requires C = 69.54, H = 7.29). This mixture was used as such, without further purification. A mixture of 1.25 g POCl3 and 1.1 g N-methylformanilide was warmed on the steam bath for several min until the color had become a deep claret. There was then added 1.5 g of the 87% pure 2,5-dimethoxyphenyl methyl selenide and the steam bath heating continued for an additional 25 min. The very tarry reaction mixture was poured into 100 mL H2O, producing fine yellow solids almost immediately. These were removed by filtration and distilled at 0.2 mm/Hg. A first fraction distilling up to 100 !C was a mixture of unreacted ethers and what appeared to be 2,5-dimethoxybenzaldehyde. A second cut distilled at 140-150 !C, solidified to a yellow solid in the receiver, and weighed 1.2 g. A small amount of this product (with mp 91-96 !C) was recrystallized from MeOH to give an analytic sample of 2,5-dimethoxy-4-(methylseleneo)benzaldehyde with a mp 88-92 !C. All efforts to achieve a tighter melting range were unsuccessful. Anal. (C10H12O3 Se) C,H. Although this benzaldehyde migrates normally on a silica gel TLC plate (Rf of 0.4 employing CH2Cl2 as a solvent) when it is once completely dried on the plate, there seems to be some irreversible reaction with the silica, and the spot will no longer move at all. To a solution of 0.85 g 2,5-dimethoxy-4-(methylseleneo)benzaldehyde in 10 mL nitromethane there was added 150 mg anhydrous ammonium acetate, and the solution was heated for 35 min on the steam bath. Removal of the volatiles under vacuum yielded brick-red solids (1.1 g) which were ground under a small amount of MeOH, filtered, and air dried. This yielded 0.88 g of solid 2,5-dimethoxy-4-methylseleneo-'-nitrostyrene with a mp of 170.5-171.5 !C. Recrystallization from IPA or from toluene gave no improvement of mp. Anal. (C11H13NO4Se) C,H. A solution of LAH (20 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 0.53 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 0.85 g 2,5-dimethoxy-4-methylseleneo-'-nitrostyrene in 20 mL hot anhydrous THF. There was an immediate discoloring. After a few minutes further stirring, the temperature was brought up to a gentle reflux on the steam bath for 0.5 h, then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of IPA and, when there was no further activity, the reaction mixture was poured into 500 mL dilute H2SO4. This was washed with 2x100 mL CH2Cl2, and then made basic with 5% NaOH. The milky aqueous phase was extracted with 2x100 mL CH2Cl2, and extensive centrifuging was required to obtain a clear organic phase. Evaporation of the pooled extracts gave 1.6 g of an oil that crystallized. This was distilled at 130-140 !C at 0.15 mm/Hg providing 0.6 g of a white oil that set to a crystalline solid melting at 87-89 !C. This was dissolved in 4 mL boiling IPA, neutralized with 8 drops of concentrated HCl and the formed solids further diluted with IPA with a little anhydrous Et2O. This crystalline product was removed by filtration, washed with Et2O, and air dried to constant weight, yielding 2,5-dimethoxy-4-methylseleneophenethylamine hydrochloride (2C-SE) with a mp of 240-241 !C. DOSAGE: perhaps 100 mg. DURATION: 6 - 8 h. QUALITATIVE COMMENTS: (with 50 mg) My tongue feels as if I had eaten hot food. Overall I got up to a plus 1, and found the effects to be completely benign. I wandered about within the Graves exhibit at the Oakland Museum but there seemed to be only minor enhancement of the visual input. (with 70 mg) The water solution of this material has an unspeakable smell. But there is no lasting taste, thank heaven. This is up to a 1.5 + and probably half again would be an effective dose. The first awareness was at 45 minutes, and the plateau lasted from 1.5 hours to about the fourth hour. I was at certain baseline at 8 hours. EXTENSIONS AND COMMENTARY: With an entirely new hetero atom in the molecule (the selenium), and with clear indications that large dosages would be needed (100 milligrams. or more), some discretion was felt desirable. There was certainly an odd taste and an odd smell. I remember some early biochemical work where selenium replaced sulfur in some amino acid chemistry, and things got pretty toxic. It might be appropriate to get some general animal toxicity data before exploring those dosages that might get to a +++. What doors are opened by the observation that the selenium analog of 2C-T is an active compound? The potency appears to be in the same ball park, whether there is a sulfur atom or a selenium atom there. From the point of view of the thing that is hung onto the hetero-atom, the selenium, the most active (and as first approximation the most safe) analogue would be the same ones that are the most potent with sulfur. These would probably be the Se-ethyl, the Se-propyl, or the Se-isopropyl, the analogs of S-ethyl, S-propyl, and S-isopropyl. If one were to be systematic, these would be called 2C-SE-2, 2C-SE-4, and 2C-SE-7. And a very special place might be held for 2C-SE-21, the analogue of 2C-T-21. Not only is this of high potential potency, but it would certainly be the first time that both fluorine and selenium are in the same centrally active drug. In fact, might not this compound, 2C-SE, be the first compound active within the human CNS with a selenium atom in it? It is certainly the first psychedelic with this atom in it! From the point of view of the hetero-atom itself, there are two more known below selenium in the Periodic Table. Each deserves some special comment. The next atom, directly below selenium, is tellurium. It is more metallic, and its com-pounds have a worse smell yet. I heard a story about a German chemist, many years ago, who was carrying a vial of dibutyl telluride in his pocket in a passenger coach from here to there in Germany, back at about the turn of the century. It fell to the floor and broke. No one could remain in the car, and no amount of decontamination could effectively make the smell tolerable. Scratch one railway coach. But the compound, 2C-TE, would be readily makeable. Dimethyl ditelluride is a known thing. However, the atom below tellurium (and at the bottom of that particular column of the Periodic Table) is the element polonium. Here one must deal in terms of theory, as far as human activity goes, since there are no non-radioactive isotopes of polonium. The only readily available isotope is that with mass 210, which is also called Radium F, and is an alpha-particle emitter. If this were ever to be put into a living organism, and if it were to seek out and hang around some particular site of action, that area would be thoroughly and completely cooked by alpha-particle emission. It would be a fun academic exercise to make 2C-PO (2,5-dimethoxy-4-methylpoloneophenethylamine), but in no way could it ever go into anyone. I knew an eminent physiologist named Dr. Hardin Jones (now dead) who always argued that the continuing use of drugs would burn out the pleasure center of the brain. It is a certainty that 2C-PO would, quite literally, do this. If I ever made it, I would call it HARDINAMINE in his honor. There was an interesting observation associated with the making of 2C-SE. In the synthesis of many of the sulfur compounds (of the 2C-T family) is was quite common to find, when there was a quantity of some organic sulfide let go as a by-product of a reaction on a warm summer night, a number of flies coming into the lab to pay a visit. On the first synthesis of the starting material for 2C-SE, a quantity of CH3SeH was let go into the environment. Within minutes, there were two beautiful dragonflies in the lab. A coincidence certainly, but somehow, it was a nice message to receive. #39 2C-T ; 2,5-DIMETHOXY-4-METHYLTHIOPHENETHYLAMINE SYNTHESIS: A solution of 149 g sodium thiosulfate in 300 mL H2O was vigorously stirred. To this there was added, over the course of 10 min, a solution of 43.2 g benzoquinone in 200 mL acetic acid. After an additional 1 h stirring at room temperature, all volatiles were removed under vacuum. The residual syrup slowly set up as crystals which, after grinding under brine, were removed by filtration and washed with additional brine. These were dissolved in MeOH, clarified by filtration through a Celite bed, and the clear filtrate stripped of solvent under vacuum. The yellow, powdery sodium 2,5-hydroxyphenylthiosulfate weighed 67 g when dry. This intermediate was dissolved in aqueous HCl (50 g in 200 mL H2O containing 400 mL concentrated HCl), cooled with an external ice bath, and treated with 250 g zinc dust added at a rate that kept the temperature below 60 !C. About 1.5 h were required, and caution must be taken concerning the poisonous hydrogen sulfide that evolves. An additional 50 mL concentrated HCl was added, and the aqueous phase decanted from the unreacted zinc metal. This was extracted with 6x100 mL Et2O, and these extracts were pooled, washed with brine, and the solvent removed under vacuum to yield 33.1 g of 2,5-dihydroxythiophenol as pale yellow needles with a mp of 118-119 !C. A solution of 118.6 g KOH pellets in 200 mL H2O was placed under N2, and to it was added 24.0 g 2,5-dihydroxythiophenol. With vigorous stirring, there was then added 160 g methyl sulfate at a rate that maintained the temperature at about 60 !C. This took about 2 h. After the addition was complete, the mixture was held at reflux for 3 h, and allowed to stir at ambient temperature overnight. It was then filtered, and the filtrate extracted with 6x100 mL Et2O, the extracts pooled, washed with 2x50 mL brine, dried over anhydrous Na2SO4, and the solvent removed under vacuum. The residue was distilled at 86-88 !C at 0.04 mm/Hg to provide 25.9 g of 2,5-dimethoxythioanisole as a white oil that crystallized on standing. Its mp was 33-34 !C. An alternate preparation of this compound follows the direct methylation of 2,5-dimethoxythiophenol (see under 2C-T-2 for the preparation of this common intermediate) with methyl iodide. To 40 mL dry CH2Cl2 there was added 6.07 g 2,5-dimethoxythioanisole, and this was cooled to 0 !C under N2. To this well stirred solution there was added 13.02 g stannic chloride over the course of 2 min. This was followed by the drop-wise addition of dichloromethyl methyl ether over 5 min, and the reaction mixture allowed to stir for an additional 15 min. After returning to room temperature, it was stirred for an additional 1 h. The reaction mixture was poured over 15 g ice, and the organic phase separated, washed with 3x25 mL 3 N HCl, with 3x50 mL brine and, after drying over anhydrous Na2SO4, the solvent was removed under vacuum. The residue was a solid and, after recrystallization from MeOH/H2O, gave 5.86 g 2,5-dimethoxy-4-(methylthio)benzaldehyde with a mp of 95-97 !C. Purification via the bisulfite complex provided an analytical sample with mp of 99-100 C. Anal. (C10H12O3S) C,H,S. The malononitrile derivative (from equal weights of the aldehyde and malononitrile in EtOH with a drop of triethylamine as catalyst) was recrystallized from an equal volume of EtOH to give orange crystals with a mp of 185-186 !C. Anal. (C13H12N2O2S) C,H,N,S. A solution of 2.1 g 2,5-dimethoxy-4-(methylthio)benzaldehyde in 7.5 mL nitromethane was treated with 0.45 g anhydrous ammonium acetate and held at steam bath temperature for 6 h. The deep red solution was stripped of solvent to give a residue that spontaneously crystallized. This was ground up under 12 mL MeOH, filtered, and washed with MeOH to yield, after air-drying, 1.7 g of 2,5-dimethoxy-4-methylthio-'-nitrostyrene as orange solids. Recrystallization from EtOH provided rust-orange colored crystals with a mp of 165.5-166 !C. Anal. (C11H13NO4S) C,H,N; S: calcd, 12.56; found, 11.96. To a gently refluxing mixture of 1.4 g LAH in 40 mL anhydrous THF under an inert atmosphere there was added, dropwise, 1.7 g 2,5-dimethoxy-4-methylthio-'-nitrostyrene in 25 mL THF. The refluxing was continued for 18 h, and the stirring continued for another day at room temperature. There was then added 1.5 mL H2O (diluted with a little THF), 1.5 mL 15% NaOH, and finally 4.5 mL H2O. The white aluminum oxide salts were removed by filtration, and the filter cake washed with THF. The filtrate and washings were combined and stripped of solvent under vacuum yielding a straw-colored residue that crystallized (mp 81-92 !C without purification). This residue was dissolved in 25 mL IPA and neutralized with concentrated HCl. The slightly pink solution spontaneously crystallized. There was added 100 mL anhydrous Et2O, and the white crystalline mass of 2,5-dimethoxy-4-methylthiophenethylamine hydrochloride (2C-T) was removed by filtration, washed with Et2O, and air dried. The final weight was 1.0 g, and had a mp of 232-237 !C. Recrystallization from EtOH provided an analytical sample with mp 240-241 !C. IPA was not a good recrystallization solvent. Anal. (C11H18ClNO2S) C,H,N,S. DOSAGE: 60 - 100 mg. DURATION: 3 - 5 h. QUALITATIVE COMMENTS: (with 60 mg) Poetry was an easy and natural thing. Both the reading of it and the writing of it. This is a potential MDMA substitute since it opens things up but it doesnUt do anything to get in the way. (with 75 mg) I am already aware at a quarter of an hour into it! It develops very quickly but very quietly. There are no visuals at all but, rather, a tactile sensitivity, with warm close feelings. This could be very erotic. There is some fantasy to music, but nothing very demanding. The viewing of pictures doesnUt do much either. The drop-off was extremely relaxed, with a good body feeling. At the fifth hour I was able to drift into an excellent, deep sleep with busy dreams. In the morning I felt refreshed and active, without apparent deficit. (with 75 mg) I got up to a thin and fragile plus two, but there was a continuing feeling of a hooded cloak brought down over my head. Nothing obvious Q it is transparent Q but it somehow separated me from everything around me. I do not think the overall experiment was worth it. (with 100 mg) Material all right, but a little bit along the lines of a 'generic' psychedelic effect. Sharper edges than 2C-B. The one true negative, which has been pretty consistent with this drug, is that there is a certain emotional removal. One teeny step removed. One is connected with feelings, certainly, but there is a tendency for the intellect to be more evident, in me, than the heart. All this is moderately so. Nothing extreme. Pretty good material, but there are more inter-esting ones. However, if you are looking for a really short one, this is one of the answers. For most people. For me, itUs still around 5 to 6 hours long. I wish we had more shorties, indeed. (with 125 mg) There was some physical tummy uncertainty, but once that was past, talking was extremely easy. This is probably really psychedelic, but I am not really sure why, as there is not much in the way of visuals. Dropping was noted just after hour number three, and I was at baseline three hours later. EXTENSIONS AND COMMENTARY: The earliest work with the sulfur atom was with the three-carbon chain materials, the ALEPHs. It was only after a considerable time of working with them, and trying to come to peace with their property of being so different from person to person as to potency, that the two-carbon homologues were looked at. Although the first of these (this compound, called 2C-T) was prepared at the same time as ALEPH-1, there was a lapse of about four years between their trials. The relatively low potency of 2C-T was a bit discouraging. But the methodical pursuit of the higher 2C-T's (to parallel the higher ALEPHs) proved to be a treasure house, and they have been explored much further than any of the ALEPHs. A note on the RTS in 2C-T. Many, in fact most, of the 2C's have their name based on the last letter of the amphetamine prototype. 2C-B from DOB, 2C-C from DOC, 2C-I from DOI, 2C-N from DON, etc. And since the original name for ALEPH-1 was DOT (the desoxy- and a thiomethyl group at the 4-position), the 2C-T naming followed this general pattern. And as a note on the subsequent numbering, they (both the ALEPHs and the 2C-TUs) are assigned numbers as they are thought up. There is no structural significance in the number but they have been, like the houses on the streets in residential Tokyo, assigned numbers in strict historical order, documenting the sequence of construction rather than the relative position down the side of the street. Both of the homologous mono-ethoxy Tweetios of 2C-T have been synthesized and evaluated. The 2-EtO-homologue of 2C-T is 2-ethoxy-5-methoxy-4-methylthiophenethylamine, or 2CT-2ETO. The benzaldehyde (2-ethoxy-5-methoxy-4-(methylthio)benzaldehyde) was an oil, the nitrostyrene intermediate had a melting point of 137-138 !C, and the final hydrochloride a melting point of 215-216 !C. The effects were felt very quickly, and there was a blurring of vision. However, the highest dose tried, 50 milligrams, was not able to produce a greater-than-plus one state, and what did occur, lasted for only 4 hours. The 5-EtO-homologue of 2C-T is 5-ethoxy-2-methoxy-4-methylthio-phenethylamine, or 2CT-5ETO. The benzaldehyde (5-ethoxy-2-methoxy-4-(methyl-thio)benzaldehyde) was impure, and had a melting point of about 66 !C, the nitrostyrene intermediate a melting point of 133-134 !C, and the final hydrochloride a melting point of 184-185 !C. There was a body awareness and modest eyes-closed visuals following the use of 30 milligrams of 2CT-5ETO. The experience was quiet, peaceful, contemplative, and insightful. The duration was perhaps 15 hours and Halcion was needed to allow sleep. There were a lot of dreams, and the next day was restful. #40 2C-T-2; 2,5-DIMETHOXY-4-ETHYLTHIOPHENETHYLAMINE SYNTHESIS: To a solution of 165 g 1,4-dimethoxybenzene in 1 L of CH2Cl2, in a well ventilated place and well stirred, there was cautiously added 300 mL chlorosulfonic acid. With about half the acid chloride added, there was a vigorous evolution of HCl gas and the generation of a lot of solids. As the addition was continued, these redissolved to form a clear, dark green solution. Towards the end of the addition, some solids were again formed. When everything was stable, there was added 2 L H2O, a few mL at a time, commensurate with the vigor of the reaction. The two phases were separated, and the aqueous phase extracted with 2x75 mL CH2Cl2. The original organic phase and the extracts were combined and the solvent removed under vacuum. The residue weighed 162 g and was quite pure 2,5-dimethoxybenzenesulfonyl chloride, a yellow crystalline solid with a mp of 115-117 !C. It need not be further purified for the next step, and it appears to be stable on storage. The sulfonamide, from this acid chloride and ammonium hydroxide, gave white crystals from EtOH, with a mp of 147.5-148.5 !C. The following reaction is also a very vigorous one and must be performed in a well ventilated place. To a solution of 400 mL 25% H2SO4 (V/V) in a beaker at least 2 L in size, there was added 54 g of 2,5-dimethoxybenzenesulfonyl chloride, and the mixture was heated on a steam bath. The yellow crystals of the acid chloride floated on the surface of the aqueous layer. There should be 80 g of zinc dust at hand. A small amount of Zn dust was placed at one spot on the surface of this chapeau. With occasional stirring with a glass rod, the temperature was allowed to rise. At about 60 or 70 !C an exothermic reaction took place at the spot where the zinc was placed. Additional dollups of zinc were added, and each small exothermic reaction site was spread about with the glass stirring rod. Finally, the reaction spread to the entire solid surface layer, with a melting of the acid chloride and an apparent boiling at the H2O surface. The remainder of the 80 g of zinc dust was added as fast as the size of the reaction container would allow. After things subsided again, the heating was continued for 1 h on the steam bath. After the reaction mixture had cooled to room temperature, it was filtered through paper in a Buchner funnel, and the residual metal washed with 100 mL CH2Cl2. The two-phase filtrate was separated, and the lower, aqueous phase was extracted with 2x75 mL CH2Cl2. The addition of 2 L H2O to the aqueous phase now made it the upper phase in extraction, and this was again extracted with 2x75 mL CH2Cl2. The organic extracts were pooled (H2O washing is more trouble than it is worth) and the solvent removed under vacuum. The light amber residue (30.0 g) was distilled at 70-80 !C at 0.3 mm/Hg to yield 25.3 g 2,5-dimethoxythiophenol as a white oil. This chemical is certainly not centrally active, but it is a most valuable precursor to all members of the 2C-T family. To a solution of 3.4 g of KOH pellets in 75 mL boiling EtOH, there was added a solution of 10.0 g 2,5-dimethoxythiophenol in 60 mL EtOH followed by 10.9 g ethyl bromide. The reaction was exothermic with the immediate deposition of white solids. This was heated on the steam bath for 1.5 h, added to 1 L H2O, acidified with HCl, and extracted with 3x100 mL CH2Cl2. The pooled extracts were washed with 100 mL of 5% NaOH, and the solvent removed under vacuum. The residue was 2,5-dimethoxyphenyl ethyl sulfide which was a pale amber oil, weighed about 10 g and which was sufficiently pure for use in the next reaction without a distillation step. A mixture of 19.2 POCl3 and 18.0 g N-methylformanilide was heated briefly on the steam bath. To this claret-colored solution there was added the above 2,5-dimethoxyphenyl ethyl sulfide, and the mixture heated an additional 20 min on the steam bath. This was then added to 500 mL of well-stirred warm H2O (pre-heated to 55 !C) and the stirring continued for 1.5 h by which time the oily phase had completely solidified to a brown sugar-like consistency. The solids were removed by filtration, and washed with additional H2O. After being sucked as dry as possible, these solids were dissolved in 50 mL boiling MeOH which, after cooling in an ice-bath, deposited almost-white crystals of 2,5-dimethoxy-4-(ethylthio)-benzaldehyde. After filtration, modest washing with cold MeOH, and air drying to constant weight, there was obtained 11.0 g of product with a mp of 86-88 !C. Recrystallization of a small sample again from MeOH provided an analytical sample with mp 87-88 !C. Anal. (C11H14O3S) C,H. To a solution of 11.0 g 2,5-dimethoxy-4-(ethylthio)benzaldehyde in 100 g of nitromethane there was added 0.5 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 80 min (this reaction progress must be monitored by TLC, to determine the point at which the starting aldehyde has been consumed). The excess nitromethane was removed under vacuum leaving a residue that spontaneously set to orange-red crystals. These were scraped out to provide 12.9 g crude 2,5-dimethoxy-4-ethylthio-'-nitrostyrene with a mp of 152-154 !C. A sample recrystallized from toluene was pumpkin colored and had a mp of 148-149 !C. Another sample from acetone melted at 149 !C sharp, and was light orange. From IPA came spectacular fluorescent orange crystals, with a mp 151-152 !C. Anal. (C12H15NO4S) C,H. A suspension of 12.4 g LAH in 500 mL anhydrous THF was stirred under He. To this there was added 12.4 g 2,5-dimethoxy-4-ethylthio-'-nitrostyrene in a little THF, and the mixture was held at reflux for 24 h. After the reaction mixture had returned to room temperature, the excess hydride was destroyed by the cautious addition of 60 mL IPA, followed by 20 mL of 5% NaOH followed, in turn, by sufficient H2O to give a white granular character to the oxides. The reaction mixture was filtered, and the filter cake washed first with THF and then with MeOH. Removing the solvents from the combined filtrate and washings under vacuum provided 9.5 g of a yellow oil. This was added to 1 L dilute HCl and washed with 2x100 mL CH2Cl2 which removed all color. After making the aqueous phase basic with 25% NaOH, it was extracted with 3x100 mL CH2Cl2, the extracts pooled, and the solvent removed under vacuum to provide 7.3 g of a pale amber oil. Distillation at 120-130 !C at 0.3 mm/Hg gave 6.17 g of a clear white oil. This was dissolved in 80 mL IPA and neutralized with concentrated HCl, forming immediate crystals of 2,5-dimethoxy-4-ethylthiophenethylamine hydrochloride (2C-T-2). An equal volume of anhydrous Et2O was added and, after complete grinding and mixing, the salt was removed by filtration, washed with Et2O, and air dried to constant weight. The resulting white crystals weighed 6.2 g. DOSAGE: 12 - 25 mg. DURATION: 6 - 8 h. QUALITATIVE COMMENTS: (with 12 mg) I donUt feel this for fully an hour, but when I do it is quite a weight. It feels good to work it through. It is OK to be with pain. You canUt eliminate it. And it is OK to contact your deep pools of anger. And all of it stems from the lack of acknowledgment. All the macho carrying on, the fights, the wars, are ways of demanding attention, and getting even for not having had it in one's life. I am experiencing more deeply than ever before the importance of acknowledging and deeply honoring each human being. And I was able to go through and resolve some judgments with particular persons. (with 20 mg) I chose 2C-T-2 at this dose level because the lateness of getting started, and I wanted a shorter experience with my daughter and her family around. I feel, however, that I have somewhat less of a body load with 2C-T-7. Today I was badly in need of the help that might possibly come from this material, and today it was my ally. I sorely needed the type of help that it afforded. The result was to work off the heavy feeling of tiredness and lack of motivation that had been hounding me. The next day I felt that I had dropped my burden. (with 20 mg) There is a neutralness to this. I am at the maximum, and I am asking myself, 'Am I enjoying this?' And the answer is, 'No, I am experiencing it.' Enjoyment seems beside the point. It is a rather intensely matter-of-fact +3. Is it interesting? Yes, but mostly in expectation of further developments. Is it inspiring? No. Is it negative? No. Am I glad I took it? Yes. Not glad. Satisfied and contented. This is a controlled +3. No threat. The body is all right. Not superbly healthy Q but OK. Of no interest, either way. If I were to define the body's state, I would have to define it in image. The image is of a not comfortable state of being clenched. Clenched? Well, carefully bound in control. (with 22 mg) A slow onset. It took an hour for a plus one, and almost another two hours to get to a +++. Very vivid fantasy images, eyes closed, but no blurring of lines between RrealityS and fantasy. Some yellow-grey patterns a la psilocybin. Acute diarrhea at about the fourth hour but no other obvious physical problems. Erotic lovely. Good material for unknown number of possible uses. Can explore for a long time. Better try 20 milligrams next time. (with 25 mg) I was at a +++ in an hour! It is most difficult to do even ordinary things. I took notes but now I canUt find them. This is much too high for anything creative, such as looking at pictures or trying to read. Talking is OK. And to my surprise I was able to get to sleep, and a good sleep, at the seven hour point. EXTENSIONS AND COMMENTARY: There is a considerable parallel between 2C-T-2 and 2C-T-7, and both have proven to be excellent tools for introspection. The differences are largely physical. With 2C-T-2, there is more of a tendency to have physical disturbances such as nausea and diarrhea. And the experience is distinctly shorter. With 2C-T-7, physical disturbances are less common, but you are into the effects for almost twice as long. Both have been frequently used in therapy as follow-ups to MDMA. A point of potential misidentification should be mentioned here. 2C-T-2 has occasionally been called, simply, T-2. This abbreviated nickname has also been used for T-2 Toxin, a mycotoxin of the Tricothecene group, formed mainly by the Fusarium spp. This is the infamous Rwarfare agentS in Southeast Asia, which was finally identified as bee feces rather than a Soviet military adventure. T-2 and 2C-T-2 are radically different compounds. All three Tweetios of 2C-T-2 have been made and looked at through human eyes. The 2-EtO-homologue of 2C-T-2 is 2-ethoxy-4-ethylthio-5-methoxyphenethylamine, or 2CT2-2ETO. The benzaldehyde (2-ethoxy-4-ethylthio-5-methoxybenzaldehyde) had a melting point of 73-75 !C, the nitrostyrene intermediate a melting point of 122-123 !C, and the final hydrochloride a melting point of 202-204 !C. Fifty milligrams was a completely effective level. The effects were felt very quickly. Vision was blurred, and there were intense eyes-closed visuals and the generation of a pleasant, contemplative mood. Baseline was re-established in five or six hours, but sleep was restless, with weird dreams. Nasal administration showed considerable variation between individuals, but a typical dose was 10 milligrams. The 5-EtO-homologue of 2C-T-2 is 5-ethoxy-4-ethylthio-2-methoxyphenethylamine, or 2CT2-5ETO. The benzaldehyde (5-ethoxy-4-ethylthio-2-methoxybenzaldehyde) had a melting point of 49 !C, but it was impure. The nitrostyrene intermediate melted at 107-108 !C, and the final hydrochloride had a melting point of 180 !C. At levels of 20 milligrams, there was a slow, gentle climb to a full effect at the third or fourth hour. The flooding of thoughts and easy conversation lasted for many hours, and on some occasion a sedative was needed at the 16 hour point. There was a feeling of being drained for the following day or two. Some intoxication was still noted in the second day. Again it is true here, as had been stated as a generality, that the 5-Tweetio analogues have potencies similar to that of the parent compound, but show a much longer duration. The nickname of Rforever yoursS had been applied. There may indeed be insight, but 24 hoursU worth is an awful lot of insight. The 2,5-DiEtO-homologue of 2C-T-2 is 2,5-diethoxy-4-ethylthiophen-ethylamine, or 2CT2-2,5DIETO. The benzaldehyde, 2,5-diethoxy-4-(ethylthio)benzaldehyde, had a melting point of 84-85 !C, the nitrostyrene intermediate a melting point of 123-124 !C, and the final hydrochloride a melting point of 220-221 !C. Levels that were evaluated from 10 to 50 milligrams were not particularly different in intensity, but were progressively longer in duration. At 50 milligrams there was a nervousness and edginess during the early part of the experience, but for the next several hours there was evident both energy and high attentiveness. There were few if any sensory alterations. There were no negatives on the following day. The duration was perhaps nine hours. #41 2C-T-4; 2,5-DIMETHOXY-4-(i)-PROPYLTHIOPHENETHYLAMINE SYNTHESIS: To a solution of 2.5 g of KOH pellets in 40 mL hot EtOH, there was added 5.4 g 2,5-dimethoxythiophenol (see under 2C-T-2 for its preparation) and 8.7 g isopropyliodide. White solids appeared in a few min, and the reaction mixture was heated on the steam bath overnight. This mixture was added to 200 mL H2O followed by additional aqueous NaOH to raise the pH to a deep purple-blue on universal pH paper. This was extracted with 3x75 mL CH2Cl2. The pooled extracts were stripped of solvent under vacuum, and the residue distilled at 100-110 !C at 0.2 mm/Hg to yield 6.9 g of 2,5-dimethoxyphenyl isopropyl sulfide as a pale yellow oil. It has a very light, pleasant smell of apples. A mixture of 4.8 g POCl3 and 4.5 g N-methylformanilide was stirred and allowed to stand at room temperature for 1 h To this claret-colored solution was added 3.0 g of 2,5-dimethoxyphenyl isopropyl sulfide, producing an exothermic reaction and immediate reddening. This was heated for 0.5 h on the steam bath, then quenched in 200 mL of warm H2O producing immediate crystals. Stirring was continued for a few min, and then the solids were removed by filtration, washed with H2O and sucked as dry as possible. When they were ground up under an equal weight of cold MeOH, refiltered and air dried, they gave 2.35 g of 2,5-dimethoxy-4-(i-propylthio)benzaldehyde as pale yellow solids (in some runs this was a pale lime-green color) with a mp of 89-90 !C. A wasteful recrystallization from MeOH gave pale yellow crystals with a mp of 90 !C sharp. To a solution of 6.7 g 2,5-dimethoxy-(i-propylthio)benzaldehyde in 40 g of nitromethane there was added 0.10 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 2 h. The excess reagent/solvent was removed under vacuum yielding 8.9 g of orange solids. This was recrystallized from 200 mL boiling MeOH providing 6.2 g of 2,5-dimethoxy-'-nitro-4-(i-propyl-thio)styrene as lustrous golden orange platelets. A solution of LAH (80 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 2.1 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 5.74 g 2,5-dimethoxy-'-nitro-4-(i-propylthio)styrene as a solid, a bit at a time. After 15 min further stirring, the temperature was brought up to a gentle reflux on the steam bath for another 15 min, then allowed to stand at room temperature overnight. After cooling again to 0 !C, the excess hydride was destroyed by the addition of 7 mL IPA followed by 6 mL 15% NaOH which was sufficent to give a white granular character. The reaction mixture was filtered and the filter cake washed with THF. The filtrate and washings were pooled, stripped of solvent under vacuum providing 3.9 g of a pale amber oil which was dissolved in 250 mL dilute H2SO4. This was washed with 3x75 mL CH2Cl2 which removed the residual yellow color. After making basic with 25% NaOH, the product was extracted with 3x75 mL CH2Cl2 and the solvent removed under vacuum to give 2.72 g of a residue which was distilled at 140-145 !C at 0.2 mm/Hg to give 2.42 g of a clear white oil. This was dissolved in 25 mL IPA, and neutralized with concentrated HCl. This gave a clear solution which, with good stirring, was diluted with 100 anhydrous Et2O to provide 2.40 g 2,5-dimethoxy-4-(i)-propyl-thiophenethylamine hydrochloride (2C-T-4) as white crystals. DOSAGE: 8 - 20 mg. DURATION: 12 - 18 h. QUALITATIVE COMMENTS: (with 8 mg) Visual effects set in at about two hours. There was much color enhancement, particularly of green, and some flowing of colors. The bright impressionistic picture of the little girl, in the bathroom, was particularly good for the visuals to take over, especially when I was concentrating on urinating. The shadows in the large picture above the fireplace would change constantly. I could not either control or turn off these effects during the middle period (3-6 hours). From the physical point of view, something early in the experience simply didnUt feel right. Both my lower legs tended to fall asleep, and this seemed to spread to my hands and lower arms. It was uncomfortable and although I was apprehensive at first it didnUt get any worse with time so I ignored it. This is not one my favorite materials, and it takes too long to wear off. If I were to do it again I would settle for 4 or 5 milligrams. It may well cut out the extremity problem amd still allow for a pleasant experience. (with 9 mg) An important characteristic of this experience was the sense of letting go and flowing with it. Just follow where it leads. This seemed to lead to a growing euphoria, a feeling of clearing out of body residues, and the handling of very impressive insights. My thinking continued to grow in clarity, visual perception was crystal clear, and it was a joy to simply look over the scenery, enjoy the beauty, enjoy the companionship, and ponder whatever came to mind. This clarity of body and mind lasted the rest of the evening with a wonderful feeling of peace and centeredness. I still felt a lot of push from the chemical at bed time, causing some tiredness, and allowing very little sleep. I kept working at what had taken place, all night, just to release the experience. (with 14 mg) Very rational, benign, and good humored. The insight and calm common to the 2C-T's are present, with less of the push of body-energy which makes 2C-T-2 difficult for some people. There are no particular visuals, but then I tend to screen them out consistently, except in cases of mescaline and LSD and psilocybin, so I canUt judge what others would experience in the visual area. The eyes-closed imagery is very good without being compelling. The decline is as gradual and gentle as the onset. I am fully capable of making phone calls and other normal stuff. Music is marvelous, and the body feels comfortable throughout. (with 14 mg) Persistent cold feet, and an uncertain stomach when moving around. Brilliant color trails reminiscent of 2C-B. But a change is occurring and I canUt talk myself out of it. There are dark corners. If I were with other people, this would bring out the worst in me, which can be pretty bad. (with 19 mg) I was caught by the TV. Leonard Bernstein conducting West Side Story. I think I know every note. This was a 1985 rehearsal with the goofs and the sweat. And now Peter, Paul and Mary, grown older along with the songs we all sang. Where Have All the Flowers Gone Q and an audience of grown-older people singing Puff the Magic Dragon like earnest children and probably crying along with me. It is good to have lived through the 60's and not to be in them now. Now there's a new song about El Salvador and itUs the battle all over again on a different field, but it will always be so, until and unless. Now, in the 80Us, I donUt get really angry anymore. I am more warrior than angry protester, and that's a much better way to be. In fact, I am quite happy to be where I am. I know a lot more about the game, and what it is, and why it is played, and I have a good idea about my part in it, and I like the part IUve chosen. (with 22 mg) The transition took place over three hours, an alert in 30 minutes followed by a slow and gentle climb. I found it difficult, not physically but mentally since I was for a while locked into the illogical and disconnected aspects of human experiences and expressions, particularly laws and pronouncements and unseeing prejudices, most of which I was picking up from reading the Sunday paper book reviews. As time went on, things became less pushy and I came to be at ease with very positive feelings about everything going on. No self-rejecting aspect at all. Sleep was excellent, but the next day things went slowly and I had to nap a bit. Next time, maybe 18 milligrams. EXTENSIONS AND COMMENTARY: There are shades of the variability of the Alephs. Some observers are overwhelmed with colors and visual activity; others volunteer their absence. And a very wide range of dosages represented, from an estimated 4 or so milligrams for full effects, to something over 20 milligrams without any loss of control. That is an unusually wide lattitude of activity. And a rich variety of effects that might be experienced. The same wide range of effective dosages was also observed with the corresponding Tweetio. The 2-EtO-homologue of 2C-T-4 is 2-ethoxy-5-methoxy-4-(i)-propylthiophenethylamine, or 2CT4-2ETO. The benzaldehyde (2-ethoxy-5-methoxy-4-(i-propylthio)benzaldehyde had a melting point of 43-44 !C, the nitrostyrene intermediate a melting point of 77-79 !C, and the final hydrochloride a melting point of 153.5-154 !C. There were practically no differences between trials at 5 milligram increments within the 10 and 25 milligram range. Each produced a gentle plus two level of effect which lasted for some 10 hours. A code name of RtendernessS was felt to be appropriate, as there was a peaceful meditative inner receptiveness and clarity noted, with an honest connection felt with those who were present during the experience. Sleep was not comfortable. I have heard 2C-T-4 referred to as T-4. There is a potent explosive used by terrorists called cyclotrimethylenetrinitramine, known by the code name RDX, or T-4. There is also a T-4 term that refers to thyroxine, an amino acid in the body. The drug 2C-T-4 is neither an explosive nor an amino acid, I am happy to say. #42 Y-2C-T-4; 2,6-DIMETHOXY-4-(i)-PROPYLTHIOPHENETHYLAMINE) SYNTHESIS: A stirred solution of 8.3 g 3,5-dimethoxy-1-chlorobenzene and 7.2 g isopropylsulfide in 100 mL anhydrous Et2O was cooled with an external ice bath, and then treated with 67 mL 1.5 M lithium diisopropylamide in hexane which was added over the course of 10 min. The reaction mixture was allowed to return to room temperature and the stirring was continued for 0.5 h. The mixture was poured into dilute H2SO4, the organic layer was separated, and the aqueous phase extracted with 3x75 mL EtOAc. The organic phases were combined, dried over anhydrous K2CO3, and the solvent removed under vacuum. The resulting 4.54 g of almost colorless oil was distilled at 85-95 !C at 0.1 mm/Hg to give 4.2 g of 3,5-dimethoxyphenyl isopropyl sulfide as a colorless oil, showing a single spot on TLC with no indication of starting chlorobenzene. The product formed a picrate salt, but this had an unsatisfactory mp character (partly melting at 45-47 !C, and then completely at about 80-90 !C). The microanalysis for this picrate was low in the carbon value, although the hydrogen and nitrogen were excellent. Anal. (C17H19N3O9S) H,N; C: calcd, 46.25; found, 44.58, 44.45. To a well-stirred solution of 4.1 g 3,5-dimethoxyphenyl isopropyl sulfide and 3.5 mL N,N,NU,NU-tetramethylethylenediamine in 25 mL anhydrous Et2O that had been cooled to -78 !C with a dry-ice/acetone bath, there was added 10 mL 2.5 M hexane solution of butyllithium. The mixture was allowed to return to room temperature, and there was added 3.5 mL DMF which caused the yellow color to progressively darken. The reaction mixture was poured into dilute H2SO4, the Et2O layer was separated, and the aqueous phase extracted with 3x75 mL EtOAc. The solvent was removed from the combined organic phases, and the residue distilled at 0.15 mm/Hg to give two fractions. One, boiling at 120-140 !C, was 0.98 g of a pale yellow mobile liquid, which was part starting sulfide and part product aldehyde by TLC. The second cut, boiling at 160-180 !C, was a viscous liquid, weighed 1.66 g, and was largely 2,6-dimethoxy-4-(i-propylthio)benzaldehyde. This formed a crystalline anil with 4-methoxyaniline (by fusing equimolar amounts of the two with a flame) which, after recrystallization from MeOH, gave fine yellow crystals with a mp of 87.5-89 !C. Anal. (C19H23NO3S) C,H. A solution of 0.8 g 2,6-dimethoxy-4-(i-propylthio)benzaldehde in 10 mL nitromethane was treated with 0.2 g anhydrous ammonium acetate and heated on the steam bath for 1 h. The excess reagent/solvent was removed under vacuum, and the residue spontaneously solidified. This was recrystallized from 5 mL MeOH to give 0.70 g 2,6-dimethoxy-'-nitro-4-(i)-propylthiostyrene as a pale yellow fluffy solid, with a mp of 83-84.5 !C. Anal. (C13H17NO4S) C,H. A solution of LAH (20 mL of a 1 M solution in THF) was cooled, under He to 0 !C with an external ice bath. With good stirring there was added 0.54 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 0.54 g 2,6-dimethoxy-'-nitro-4-(i)-propylthiostyrene in a small volume of anhydrous THF. The color was discharged immediately. After a few minutes further stirring, the temperature was brought up to a gentle reflux on the steam bath for about 10 min, and then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of IPA followed by sufficent 15% NaOH to give a white granular character to the oxides, and to assure that the reaction mixture was basic. The reaction mixture was filtered, and the filter cake washed well with THF. The filtrate was stripped of solvent under vacuum and the residue dissolved in 100 mL of dilute H2SO4. This was washed with 2x50 mL CH2Cl2 (the washes were saved, see below), made basic with aqueous NaOH, and then extracted with 2x50 mL CH2Cl2. The residue remaining after the removal of the solvent was distilled at 130-140 !C at 0.05 mm/Hg to give 0.11 g of a white oil. This was dissolved in 10 mL IPA, neutralized with 5 drops of concentrated HCl and diluted with 50 mL anhydrous Et2O. After filtration of the formed crystals, Et2O washing, and air drying, there was obtained 80 mg of 2,6-dimethoxy-4-(i)-propylthiophenethylamine hydrochloride (y-2C-T-4) as fine white crystals. The removal of the solvent from the CH2Cl2 washes of the dilute H2SO4 solution gave a H2O-soluble white solid that proved to be the sulfate salt of the product. This provided, after making the H2O solution basic, extraction with CH2Cl2, and solvent removal, the free base that was converted, as described above, to a second crop of the hydrochloride salt. DOSAGE: above 12 mg. DURATION: probably short. QUALITATIVE COMMENTS: (with 8 mg) I might actually be up to a plus 1, and with a very good feeling. But I cannot say how long it lasted, and it was probably pretty short. It just sort of faded away. (with 12 mg) At the 25 minute point I am reminded of the experiment, and in another quarter hour I am into something. Will this be another forever threshold? I feel very good, but there is no sparkle. EXTENSIONS AND COMMENTARY: Here is another example of the presentation of a compound for which there has not yet been an effective level determined. Why? For a very good reason. This is an example of a whole class of compounds that I have called the pseudos, or the y-compounds. Pseudo- as a prefix in the literary world generally stands for Rfalse.S A pseudopod is a thing that looks like a foot, but isnUt one. A pseudonym is a fictitious name. But in chemistry, it has quite a different meaning. If something has a common name, and there is a second form (or isomer, or shape, or orientation) that is possible and it doesnUt have a common name, it can be given the name of the first form with a Rpseudo-S attached. Ephedrine is the erythro-isomer of N-methyl-'-hydroxyamphetamine. There is a second stereoisomer, the threo- isomer, but it has no trivial name. So it is called pseudoephedrine, or the RSudafedS of sinus decongestant fame. The pseudo-psychedelics are the 2,4,6-trisubstituted counterparts of the 2,4,5-trisubstituted psychedelics. Almost all of the 2,5-dimethoxy-4-something-or-other compounds are active and interesting whether they be phenethylamines or amphetamines, and it is an exciting fact that the 2,6-dimethoxy-4-something-or-other compounds are going be just as active and just as interesting. A number of examples have already been mentioned. TMA-2 is 2,4,5-trimethoxyamphetamine (a 2,5-dimethoxy-substituted compound with a methoxyl at the 4-position). The pseudo- analogue is TMA-6 (2,4,6-trimethoxyamphetamine) and it is every bit as potent and fascinating. Z-7 could be called pseudo-DOM, and although it is quite a bit down in potency, it is an active drug and will both demand and receive much more clinical study some day. Will the other 2,4,5-things spawn 2,4,6-things that are active? Without a shadow of a doubt. Chemically, they are much more difficult to synthesize. The 2,5-dimethoxy orientation made the 4-position a natural and easy target. The 2,6-dimethoxy orientation pushes for 3-substitution, and the 4-position is completely unnatural. Tricks are needed, but tricks have now been found. The above synthesis of pseudo-2C-T-4 shows one such trick. This is, in my opinion, the exciting chemistry and psychopharmacology of the next decade. Well over half of all the psychedelic drugs mentioned in Book II are 2,4,5-trisubstituted compounds, and every one of them has a (potentially active) 2,4,6-pseudo-counterpart. It goes yet further. The antidepressant series of RAriadneS compounds are 1-phenyl-2-aminobutanes. But the 1-phenyl is again a 2,4,5-trisubstituted compound. The 2,4,6-isomer will give rise to a pseudo-Ariadne family, and I will bet that they too will be antidepressants. The 1-phenyl-2-aminobutane analog of y-2C-T-4 is the 2,4,6-analogue and it has been prepared as far as the nitrostyrene. It has not yet been reduced, so it is not yet been evaluated, but it could be a most remarkable psycho-pharmacological probe. And it goes yet yet further. Think back to the six possible TMAUs. TMA and TMA-3 were relatively inactive. And TMA-2 and TMA-6 were the interesting ones. The first gave rise to the last twenty years of psychedelic chemistry, and the other (as speculated upon above) will give rise to the forthcoming ten years. But what of TMA-4 and TMA-5? Both showed activity that was more than TMA but less than that of the -2 or -6 isomers. Could they, some day, provoke yet other families of psychedelics? Maybe the 3-position of these two might be focal points of leverage as to psychological activity. What are the letters that follow y in the Greek alphabet? If I remember correctly, the next letter is the last letter, omega. So, I guess that Nature is trying to tell us something, that the -4 and -5 isomers will not engender interesting families. What a pity. The chemistry is so unthinkably difficult that it would have been a true challenge. My next incarnation, maybe? #43 2C-T-7; 2,5-DIMETHOXY-4-(n)-PROPYLTHIOPHENETHYLAMINE SYNTHESIS: To a solution of 3.4 g of KOH pellets in 50 mL hot MeOH, there was added a mixture of 6.8 g 2,5-dimethoxythiophenol (see under the recipe for 2C-T-2 for its preparation) and 7.4 g (n)-propylbromide dissolved in 20 mL MeOH. The reaction was exothermic, with the deposition of white solids. This was heated on the steam bath for 0.5 h, added to 800 mL H2O, additional aqueous NaOH added until the pH was basic, and extracted with 3x75 mL CH2Cl2. The pooled extracts were washed with dilute NaOH, and the solvent removed under vacuum. The residue was 2,5-dimethoxyphenyl (n)-propyl sulfide which was obtained as a pale yellow oil, and which weighed 8.9 g. It had a light pleasant fruity smell, and was sufficiently pure for use in the next reaction without distillation. A mixture of 14.4 g POCl3 and 13.4 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 8.9 g of 2,5-dimethoxyphenyl (n)-propyl sulfide, and the mixture heated an additional 25 min on the steam bath. This was then added to 800 mL of well-stirred warm H2O (pre-heated to 55 !C) and the stirring continued until the oily phase had completely solidified (about 15 minutes). The resulting brown sugar-like solids were removed by filtration, and washed with additional H2O. After sucking as dry as possible, they were dissolved in an equal weight of boiling MeOH which, after cooling in an ice-bath, deposited pale ivory colored crystals. After filtration, modest washing with cold MeOH, and air drying to constant weight, there was obtained 8.3 g of 2,5-dimethoxy-4-(n-propyl-thio)benzaldehyde with a mp of 73-76 !C. Recrystallization from 2.5 volumes of MeOH provided a white analytical sample with mp 76-77 !C. The NMR spectrum in CDCl3 was textbook perfect, with the two aromatic protons showing singlet signals at 6.81 and 7.27 ppm, giving assurance that the assigned location of the introduced aldehyde group was correct. To a solution of 4.0 g 2,5-dimethoxy-(n-propylthio)benzaldehyde in 20 g of nitromethane there was added 0.23 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 1 h. The clear orange solution was decanted from some insoluble material and the excess nitromethane removed under vacuum. The orange-yellow crystalline material that remained was crystallized from 70 mL boiling IPA which, on slow cooling, deposited 2,5-dimethoxy-'-nitro-4-(n)-propylthiostyrene as orange crystals. After their removal by filtration and air-drying to constant weight, they weighed 3.6 g, and had a mp of 120-121 !C. Anal. (C13H17NO4S) C,H. A solution of LAH (132 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 3.5 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 8.4 g 2,5-dimethoxy-'-nitro-4-(n)-propylthiostyrene in 50 mL anhydrous THF. There was an immediate loss of color. After a few min further stirring, the tem-perature was brought up to a gentle reflux on the steam bath, then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of IPA (21 mL required) followed by sufficent 5% NaOH to give a white granular character to the oxides, and to assure that the reaction mixture was basic (15 mL was used). The reaction mixture was filtered and the filter cake washed first with THF and then with IPA. The filtrate and washes were combined and stripped of solvent under vacuum providing about 6 g of a pale amber oil. Without any further purification, this was distilled at 140-150 !C at 0.25 mm/Hg to give 4.8 g of product as a clear white oil. This was dissolved in 25 mL IPA, and neutralized with concentrated HCl forming immediate crystals of the hydrochloride salt in the alcohol solvent. An equal volume of anhydrous Et2O was added, and after complete grinding and mixing, 2,5-dimethoxy-4-(n)-propylthiophenethylamine hydrochloride (2C-T-7) was removed by filtration, Et2O washed, and air dried to constant weight. The resulting spectacular white crystals weighed 5.2 g. DOSAGE: 10 - 30 mg. DURATION: 8 - 15 h. QUALITATIVE COMMENTS (with 20 mg) A wonderful day of integration and work. Took about 2 hours for the onset. Some nausea on and off Q that seemed to cycle periodically throughout the day. Visuals were great, much like mescaline but less sparkly. Lots of movement and aliveness Q velvety appearance and increased depth perception. Neck and shoulder tension throughout the day along with legs. I would periodically notice extreme tightness of muscles, and then relax. Working was very integrative. Back and forth constantly between wonderful God-space Q similar to MDMA but more grounded Q then always back to sadness. I felt that it really showed me where I was unfinished, but with self-loving and tolerance. Tremendous processing and letting go. Seeing things very clearly and also able to laugh at my trips. Lots of singing. In spite of shoulder tension, vocal freedom and facility were very high. I felt my voice integrated and dropped in a way it never had before, and that remained for several days. Able to merge body, voice, psyche and emotions with music and then let go of it as a role. I also realized and gave myself permission to do whatever it takes to get free. I let go of Dad with tragic arias. The next day I let go of Mom by singing Kaddish for her, and merging with it. (with 20 mg) I lay down with music, and become engrossed with being as still as possible. I feel that if I can be totally, completely still, I will hear the inner voice of the universe. As I do this, the music becomes incredibly beautiful. I see the extraordinary importance of simply listening, listening to everything, to people and to nature, with wide open receptivity. Something very, very special happens at the still point, so I keep working on it. When I become totally still, a huge burst of energy is released. And it explodes so that it takes enormous effort to quiet it all down in order to be still again. Great fun. (with 25 mg) This was a marvelous and strange evening. This 2C-T-7 is good and friendly and wonderful as I remember it. I think it is going to take the place of 2C-T-2 in my heart. It is a truly good material. I got involved with a documentary on television. It was about certain people of Bolivia, people living in the high mountains and about a small village which Q perhaps alone among all the places in the country Q maintains the old Inca ways, the old traditions, the old language. Which is, I gather, against the law in Bolivia. It showed a yearly meeting of shamans and it was quite clear that hallucinogens played a major part in this meeting. The shaman faces, male and female, were startling in their intensity and earthy depth. The Virgin Mary is worshipped as another version of the ancient Pacha Mama, the Earth Mother. Wonderful dark, vivid look at places and people who are not usually to be seen or even known about. (with 30 mg) The visuals have an adaptable character to them. I can use them to recreate any hallucinogenic substance I have known and loved. With open eyes, I can go easily into LSD flowing visuals, or into the warm earth world of Peyote, or I can stop them altogether. With closed eyes, there are Escher-like graphics with a lot of chiaroscuro, geometric patterns with oppositional play of sculptured light and dark values. Green light. EXTENSIONS AND COMMENTARY: If all the phenethylamines were to be ranked as to their acceptability and their intrinsic richness, 2C-T-7 would be right up there near the top, along with 2C-T-2, 2C-B, mescaline and 2C-E. The range is intentionally extended on the lower side to include 10 milligrams, as there have been numerous people who have found 10 or so milligrams to be quite adequate for their tastes. One Tweetio related to 2C-T-7 has been made and evaluated. This is the 2-EtO-homologue of 2C-T-7, 2-ethoxy-5-methoxy-4-(n)-propylthiophenethyl-amine, or 2CT7-2ETO. The benzaldehyde (2-ethoxy-5-methoxy-4-(n-propyl-thio)benzaldehyde had a melting point of 69-71 !C, the nitrostyrene intermediate a melting point of 106-106.5 !C, and the final hydrochloride a melting point of 187-189 C!. At the 20 milligram level, the effects were felt quickly, and the eyes-closed visuals were modest but real. It was very short-lived, with baseline recovery at about the fifth hour. The next day there was an uncomfortable headache which seemed on an intuitive level to be an after-effect of the compound. The unusual properties of a number of N-methyl-N-(i)-propyltryptamines suggested the possibility of something like a similar set of N-methyl-N-(i)-propylphenethylamines. Why not try one from 2C-T-7? The thought was, maybe N-methylate this compound, then put on an isopropyl group with reductive alkylation, using acetone as the carbon source and sodium cyanoborohydride. Towards this end, the free base of 2C-T-7 (from one gram of the hydrochloride) was refluxed for 2 h in 1.3 g butyl formate, and on removing the solvent/reactant the residue spontaneously crystallized. This formamide (0.7 g) was reduced with lithium hydride in cold THF to provide 2,5-dimethoxy-4-(n)-propyl-N-methyl-phenethylamine, METHYL-2C-T-7, which distilled at 150-170 !C at 0.4 mm/Hg. A very small amount of the hydrochloride salt was obtained (65 milligrams) and it had a brown color. Too small an amount of an impure product; the entire project was dropped. #44 2C-T-8; 2,5-DIMETHOXY-4-CYCLOPROPYLMETHYLTHIOPHENETHYLAMINE SYNTHESIS: To a solution of 2.8 g of KOH pellets in 25 mL hot MeOH, there was added a mixture of 5.9 g 2,5-dimethoxythiophenol (see under 2C-T-2 for its preparation) and 5.0 g of cyclopropylmethyl bromide. There was an immediate exothermic reaction with spontaneous boiling and the formation of white crystals. This was heated on the steam bath for 4 h, and then added to 400 mL of H2O. After extraction with 3x75 mL CH2Cl2, the pooled extracts were washed first with dilute NaOH, then with saturated brine, then the solvent was removed under vacuum. The residue, 8.45 g of crude 2,5-dimethoxyphenyl cyclopropyl methyl sulfide, was distilled at 120-140 !C at 0.3 mm/Hg to give a white oil weighing 7.5 g. A mixture of 13.5 g POCl3 and 13.5 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 7.28 g of 2,5-dimethoxyphenyl cyclopropylmethyl sulfide, and the spontaneously exothermic mixture was heated for an additional 10 min on the steam bath, and then quenched in 400 mL of 55 !C H2O with good stirring. After a few minutes a reddish solid phase separated. This was removed by filtration, and washed with additional H2O. After sucking as dry as possible, this 8.75 g of ochre-colored solid was dissolved in 14 mL of boiling MeOH, and after cooling, filtering, washing sparsely with MeOH, and air drying, gave 7.27 g of white solid crystals of 2,5-dimethoxy-4-(cyclopropylmethylthio)benzaldehyde. The proton NMR spectrum was impeccable; CHO 9.38, ArH 7.27, 6.81 2 s., OCH3 3.93, 3.90 2 s., SCH2 t. 2.96, CH2, m. 1.72, and CH2, t. 1.11. To a solution of 6.6 g 2,5-dimethoxy-4-(cyclopropylthio)benzaldehyde in 82 g of nitromethane there was added 0.12 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 6 h. The reaction mixture was allowed to stand overnight producing a heavy crystallization crop. Filtration, washing lightly with MeOH, and air drying gave 4.72 g of orange crystals of 2,5-dimethoxy-4-cyclopropylmethylthio-'-nitrostyrene as yellow crystals. The evaporation of the mother liquors and grinding of the resulting solids with MeOH provided another 2.0 g of the product. A solution LAH (40 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 1.05 mL 100% H2SO4 dropwise over 10 min, to minimize charring. This was followed by the addition of 2.95 g 2,5-dimethoxy-4-cyclopropylmethylthio-'-nitrostyrene as a solid, over the course of 10 min. After a few min further stirring, the temperature was brought up to a gentle reflux on the steam bath, then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of 6 mL IPA followed by 3 mL 15% NaOH which gave the aluminum oxide as a curdy white solid. The reaction mixture was filtered, and the filter cake washed with additional THF. The filtrate and washes were stripped of solvent under vacuum providing about 1.8 g of a colorless oil. The addition of dilute H2SO4 produced a thick mass of white solids. This was washed with CH2Cl2, and the remaining aqueous phase, still containing solids, was made basic with 25% NaOH. The aqueous phase was extracted with 3x75 mL CH2Cl2, and the combined extracts stripped of solvent under vacuum. The result was 1.4 g of colorless oil. This was distilled at 150-165 !C at 0.2 mm/Hg to give 1.2 g of a white oil. This was dissolved in 6 mL IPA, neutralized with 0.6 mL concentrated HCl producing spontaneous white crystals. These were diluted with 8 mL additional IPA, and suspended under 60 mL anhydrous Et2O to provide, after filtering and air drying, 1.13 g of 2,5-dimethoxy-4-cyclo-propylmethylthiophenethylamine hydrochloride (2C-T-8) as white crystals. DOSAGE: 30 - 50 mg. DURATION: 10 - 15 h. QUALITATIVE COMMENTS: (with 30 mg) Bad taste, worse smell. But I like it. I can paint easily, and wouldnUt hesitate to take a little more next time, but this is enough with no one to talk to. Manual dexterity good. Body rather warm. WouldnUt mind fooling around. In retrospect, it has a smooth onset, and is not too stimulating. This is a good one. (with 40 mg) This is beginning to develop at one and a half hours into it. High energy, good feeling. I have had a heavy, dense feeling between me and my work for several days now, but this is rapidly dissolving, and with this loss, the day continues into one of the most remarkable experiences I have ever had. Excellent feelings, tremendous opening of insight and understanding, a real awakening as if I had never used these materials effectively before. For the next several hours it was an internal journey for me; I wished to interact with myself. I cannot recall all the details, but I did review many aspects of myself and my personal relations. I know that I am the better for all of this. (with 40 mg) I first noted the effects at three quarters of an hour, and at two hours I have pain in my sinuses. My head is split in two Q this is not being two or three different people Q this is one person with a head living in two different universes at the same time. Not a crisis experience, but one of extreme and prolonged discomfort. Hypersensitivity to light, noise, motion, with the belief that it would not go away when the chemical wore off. My visual and spatial perceptions were divided in two along a vertical axis, with both halves moving in uncoordinated ways. A feeling that the eyes were working independently of each other. Nausea without vomiting, even when I tried to. Vertigo became intolerable if I closed my eyes or lay down, so I felt that I would never lie down or close my eyes again. Problems with 'boundaries.' The outside environment seemed to be getting inside my head. The parts of myself seemed to either separate uncontrollably or run together into someone I didnUt know. A late movie, and Tranxene, and a little sleep all helped me out of this. However, a buzzing in the head, an uncertain balance, and an out-of-it feeling lasted for 3 days, and was still faintly present after a week. (with 43 mg) For the first two hours I rocked in place and felt quite happy not trying to 'do' anything useful or expected, but watched some excellent programs on TV. Later I sat at the typewriter and felt the energy and the opening of the particular kind of thinking-connection that I associate with 2C-T-2. I felt this very strongly; I was fully into my own energy and capable of being aggressive if I decided to. I was very good humored and completely anchored to the earth. In the late evening I went to bed and felt that I would not allow myself to sleep, since the tendency to go completely out of conscious body was quite strong. However, before I could get up and continue happily writing, as I intended, I fell asleep. I slept thoroughly, well, and woke up the next day with good energy and a willingness to get on with the day. (with 50 mg) The whole experience was somewhat negative, self-doubting, paranoid. Basically, I am not in a good place. No constructive values ever knit, and although there was a lot of talking, nothing positive developed. I was glad of sleep at about twelve hours into it, and this aspect of it was completely friendly. Next day, no deficit. Strange. Maybe too much. EXTENSIONS AND COMMENTARY: With 2C-T-8, there are as many negatives as there are positives, and the particular substitution pattern is not one to set the world on fire. The first step was made towards the synthesis of the 3-carbon counterpart, 2,5-dimethoxy-4-cyclopropylmethylthioamphetamine, ALEPH-8. The above benzaldehyde (2.2 g) was cooked overnight on the steam bath in nitroethane (20 mL) containing ammonium acetate (0.4 g) and when the solvent was removed, the residue was converted to orange crystals by the addition of a little MeOH. This was not pursued further. Although the cyclopropylmethyl group was quite something on the mescaline oxygen atom, it is less appealing on the 2C-T-X sulfur atom, and there is even less enthusiasm to put it into an ALEPH. That's the way it is, and who could have guessed! #45 2C-T-9; 2,5-DIMETHOXY-4-(t)-BUTYLTHIOPHENETHYLAMINE SYNTHESIS: To a well-stirred ice-cold suspension of 2.8 g p-dimethoxybenzene and 3.2 mL N,N,NU,NU-tetramethylethylenediamine in 100 mL petroleum ether under an inert atmosphere of He, there was added 13 mL of a 1.6 N solution of butyllithium in hexane. The suspended dimethoxybenzene became opaque and there was a pale yellow color generated. The reaction mixture was warmed to room temperature which converted it to light white solids. After an additional 0.5 h stirring, there was added, slowly, 3.6 g of di-(t)-butyldisulfide. The yellow color deepened, the solids dissolved and, after 1 h, the color was a clear deep brown. This solution was poured into 100 mL dilute HCl and the organic phase was separated. The aqueous fraction was extracted with 3x75 mL CH2Cl2. The combined organic phases were washed with dilute aqueous NaOH, with H2O, and then stripped of solvents under vacuum. The residue was distilled at 95-105 !C at 0.5 mm/Hg to provide 3.7 g of 2,5-dimethoxyphenyl (t)-butyl sulfide as a white, mobile liquid. Anal. (C12H18O2S) C,H. A solid derivative was found in the nitration product, 2,5-dimethoxy-4-(t)-butylthio-1-nitrobenzene, which came from the addition of 0.11 mL of concentrated HNO3 to a solution of 0.23 g of the above sulfide in 5 mL ice cold acetic acid. Dilution with H2O provided yellow solids which, on recrystallization from MeOH, had a mp of 92-93 !C. Anal. (C12H17NO4S) C,H. Attempts to make either the picrate salt or the sulfonamide derivative were not satisfactory. A mixture of 72 g POCl3 and 67 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 28 g of 2,5-dimethoxyphenyl (t)-butyl sulfide, and the mixture heated for 10 min on the steam bath. This was then added to 1 L of H2O and stirred overnight. The residual brown oil was separated from the water mechanically, and treated with 150 mL boiling hexane. The hexane solution was decanted from some insoluble tars, and on cooling deposited a dark oil which did not crystallize. The remaining hexane was removed under vacuum and the residue combined with the above hexane-insoluble dark oil, and all distilled at 0.2 mm/Hg. An early fraction (70-110 !C) was largely N-methyl-formanilide and was discarded. Crude 2,5-dimethoxy-4-(t-butylthio)benzaldehyde came over at 120-130 !C and weighed 12.0 g. This was never satisfactorily crystallized despite the successful formation of seed. It was a complex mixture by TLC, containing several components. It was used for the next step as the crude distilled fraction. To a solution of 10 g impure 2,5-dimethoxy-(t-butylthio)benzaldehyde in 75 mL of nitromethane there was added 1.0 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath 1.5 h. Removal of the excess solvent/reagent under vacuum produced an orange oil that was (not surprisingly) complex by TLC and which would not crystallize. A hot hexane solution of this oil was allowed to slowly cool and stand at room temperature for several days, yielding a mixture of yellow crystals and a brown viscous syrup. The solids were separated and recrystallized from 40 mL MeOH to give 3.7 g 2,5-dimethoxy-4-(t)-butylthio-'-nitrostyrene as fine lemon-yellow crystals, with a mp of 93-94 !C. A second crop of 1.4 g had a mp of 91-92 !C. Anal. (C14H19NO4S) C,H. A solution of LAH (70 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 2.1 mL 100% H2SO4 dropwise, over the course of 20 min. This was followed by the addition of 4.7 g 2,5-dimethoxy-4-(t)-butylthio-'-nitrostyrene in 20 mL anhydrous THF. There was an immediate loss of color. After a few min further stirring, the mixture was allowed to come to room temperature, and the stirring was continued for 5 h. The excess hydride was destroyed by the cautious addition of 10 mL IPA followed by 6 mL 15% NaOH and finally 6 mL H2O. The loose white solids were removed by filtration, and the filter cake washed with THF. The filtrate and washes were combined and, after stripping off the solvent under vacuum, there was obtained 4.66 g of a pale yellow oil. Without any further purification, this was distilled at 0.2 mm/Hg. A first fraction came over at up to 120 !C and was a light colorless oil that was not identified. The correct product distilled at 130-160 !C as a pale yellow viscous oil that weighed 1.66 g. This was dissolved in 10 mL IPA, neutralized with 20 drops of concentrated HCl and diluted with 80 mL anhydrous Et2O. After standing a few min there was the spontaneous generation of white crystals of 2,5-dimethoxy-4-(t)-butylthiophenethylamine hydrochloride (2C-T-9) which were removed by filtration, and air dried. The weight was 1.10 g. DOSAGE: 60 - 100 mg. DURATION: 12 - 18 h. QUALITATIVE COMMENTS: (with 90 mg) 2C-T-9 tastes the way that old crank-case motor oil smells. I was up to something above a plus two at the third hour. Although there were no visuals noted, I certainly would not choose to drive. Somehow this does more to the body than to the head. I feel that the effects are waning at maybe the sixth hour, but there is a very strong body memory that makes sleeping difficult. Finally, at sometime after midnight and with the help of a glass of wine, some sleep. (with 125 mg) There was a steady climb to a +++ over the first couple of hours. So far, the body has been quite peaceful without any strong energy push or stomach problems, although my tummy insists on being treated with quiet respect, perhaps out of habit, perhaps not. At the fifth hour, the body energy is quite strong, and I have the choice of focusing it into some activity, such as love-making or writing, or having to deal with tapping toes and floor-pacing. For a novice this would be a murderously difficult experience. Too much energy, too long a time. I suppose I could get used to it, but let me judge by when I get to sleep, and just what kind of sleep it is. It turned out that sleep was OK, but for the next couple of days there was a continuing awareness of some residue in the body Q some kind of low-level poisoning. I feel in general that there is not the excitement or creativity to connect with, certainly not enough to justify the cost to the body. EXTENSIONS AND COMMENTARY: The three-carbon analog of 2C-T-9 (this would be one of the ALEPH series) has never been made and, for that matter, none of the higher numbered 2C-T's have had the amphetamine counterparts synthesized. They are, as of the present time, unknown compounds. This nifty reaction with di-(t)-butyl disulfide worked so well, that three additional disulfides that were at hand were immediately thrown into the chemical program, with the quick assignment of the names 2C-T-10, 2C-T-11, and 2C-T-12. The lithiated dimethoxybenzene reaction with 2,2-dipyridyl disulfide produced 2,5-dimethoxyphenyl 2-pyridyl sulfide which distilled at 135-150 !C at 0.4 mm/Hg and could be recrystallized from cyclohexane containing 2% EtOH to give a product that melted at 66-67.5 !C. Anal. (C13H13NO2S) C,H. This would have produced 2,5-dimethoxy-4-(2-pyridylthio)phenethylamine (2C-T-10) but it was never pursued. The same reaction with di-(4-bromophenyl) disulfide produced 2,5-dimethoxyphenyl 4-bromophenyl sulfide which distilled at 150-170 !C at 0.5 mm/Hg and could be recrystallized from MeOH to give a product that melted at 72-73 !C. Anal. (C14H13BrO2S) C,H. This was being directed towards 2,5-dimethoxy-4-(4-bromophenylthio)phenethylamine (2C-T-11) but it also was abandoned. The same reaction with N,N-dimorpholinyl disulfide produced virtually no product at all, completely defusing any plans for the synthesis of a novel sulfur-nitrogen bonded base 2,5-dimethoxy-4-(1-morpholinothio)phenethylamine (2C-T-12). One additional effort was made to prepare a 2C-T-X thing with a sulfur-nitrogen bond. The acid chloride intermediate in the preparation of 2,5-dimethoxythiophenol (as described in the recipe for 2C-T-2) is 2,5-dimethoxybenzenesulfonyl chloride. It reacted smoothly with an excess of diethylamine to produce 2,5-dimethoxy-N,N-diethylbenzenesulfonamide which distilled at 155 !C at 0.13 mm/Hg and which could be recrystallized from a 4:1 mixture of cyclohexane/benzene to give a product with a melting point of 41-42 !C and an excellent proton NMR. This amide proved totally refractory to all efforts at reduction, so the target compound, 2,5-dimethoxy-4-diethylaminothiophenethylamine, has not been made. It has not even been given a 2C-T-X number. #46 2C-T-13; 2,5-DIMETHOXY-4-(2-METHOXYETHYLTHIO)PHENETHYLAMINE SYNTHESIS: To a solution of 3.25 g of KOH pellets in 25 mL hot MeOH, there was added 6.8 g of 2,5-dimethoxythiophenol (see under 2C-T-2 for its preparation) followed by 4.73 g of 2-methoxyethylchloride. This mixture was heated on the steam bath for 0.5 h, then added to 500 mL H2O. This very basic aqueous phase was extracted with 3x100 mL CH2Cl2, the extracts pooled, and back-washed with 5% NaOH. The solvent was removed under vacuum to give 8.82 g of a white oil. Distillation gave 2,5-dimethoxyphenyl 2-methoxyethyl sulfide with a bp 115-125 !C at 0.3 mm/Hg, and a weight of 6.65 g. A mixture of 10 g POCl3 and 10 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 6.16 g of 2,5- dimethoxyphenyl 2-methoxyethyl sulfide. There was an immediate exothermic reaction and gas evolution. The mixture was heated for 15 min on the steam bath, at which time there was no starting sulfide present by TLC. This was then added to 500 mL of well-stirred warm H2O (pre-heated to 55 !C) and the stirring continued until only a thin oily phase remained. This was extracted with CH2Cl2, the extracts were combined, and the solvent removed under vacuum. The residue was extracted with 5 sequential 20 mL portions of boiling hexane which deposited crystals on cooling. Filtering gave a total of 4.12 g crystalline solids. Recrystallization from MeOH gave a poor yield of a cream-colored crystal with a mp of 68-69 !C. A more efficient purification was achieved by distillation (155-168 !C at 0.3 mm/Hg) yielding 3.50 g of 2,5-dimethoxy-4-(2-methoxyethylthio)benzaldehyde as a pale yellow solid, with a mp of 67-68 !C. A faster moving (by TLC) trace component with an intense fluo-rescence persisted throughout the entire purification scheme, and was still present in the analytical sample. Anal. (C12H16O4S) C,H. To a solution of 3.41 g 2,5-dimethoxy-4-(2-methoxyethylthio)benzaldehyde in 50 g of nitromethane there was added 0.11 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 2 h, at which time the starting aldehyde had largely disappeared by TLC (silica gel plates with CH2Cl2 as the developing solvent) and a faster moving nitrostyrene product was clearly visible. The clear orange solution was stripped of the excess nitromethane under vacuum producing a yellow oil that crystallized yielding 3.97 g of a yellow solid with a mp of 99-104 !C. Recrystallization of a small sample from MeOH produced (when dry) yellow electrostatic crystals of 2,5-dimethoxy-4-(2-methoxyethylthio)-'-nitrostyrene with a mp of 107 !C sharp. From IPA the product is a burnished gold color with the mp 106-107 !C. Anal. (C13H17NO5S) C,H. A solution of LAH (40 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 1.05 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 3.07 g 2,5-dimethoxy-4-(2-methoxyethylthio)-'-nitrostyrene in small portions, as a solid, over the course of 10 min. There was a considerable amount of gas evolved, and a little bit of charring. After a few min further stirring, the temperature was brought up to a gentle reflux on the steam bath, and then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of 8 mL IPA followed by 3 mL 15% NaOH which gave the reaction mixture a curdy white granular character. The reaction mixture was filtered, the filter cake washed with THF, and filtrate and washes were stripped of solvent under vacuum providing about 3 g of a pale amber oil. This was dissolved in about 40 mL CH2Cl2 and extracted with 200 mL dilute H2SO4 in three portions. All of the color remained in the organic phase. The pooled aqueous extracts were washed with CH2Cl2, then made basic with 25% NaOH, extracted with 3x75 mL CH2Cl2, and the combined extracts pooled and stripped of solvent under vacuum. The 2 g pale yellow oily residue was distilled at 155-165 !C at 0.2 mm/Hg to give 1.23 g of a clear white oil. This was dissolved in IPA, neutralized with concentrated HCl, and diluted with anhydrous Et2O to produce crystals of 2,5-dimethoxy-4-(2-methoxyethylthio)phenethylamine hydrochloride (2C-T-13). After filtration, washing with Et2O, and air drying, this white crystalline product weighed 0.89 g. DOSAGE: 25 - 40 mg. DURATION: 6 - 8 h. QUALITATIVE COMMENTS: (with 25 mg) I felt it was somewhat noisy as we went into the experience. This noisiness lasted only about an hour, then stopped. At the peak, which seemed to be at about 1 to maybe 1.5 hours, some eyes-closed visuals appeared. There was a white field with colored visuals, at times geometric in shape. These eye-closed images were pleasant and I enjoyed them when I did not concern myself with, or listen to, the conversation. There was an eyes-open change in color, the ivy became a little lighter or maybe a little stronger in color. IUm not sure which. I felt there was a gradual diminishing of activity (whatever that undefined activity was) starting at 2 to 2.5 hours, and coming close to baseline at 6 PM. The descent was pleasant and I would say pleasurable. The experience did not lead to any confusion which I sometimes notice in other experiences. There was no problem with anorexia. We ate constantly during the experience. The grapes and other fruit were lovely. This is one of the few times I would say that I would try a higher dose. Maybe 30 or 33 milligrams. I suspect the experience would be similar, with just a heightened peak at 1 hour and perhaps a little more body effect. It may well be one to try with one's wife. (with 28 mg) There was a strange, disturbing twinge exactly eight minutes after starting this, that asked me, TShould I have done this?U I answered, TYesU and the twinge disappeared. And then there was nothing until the expected time of development, at a half hour when I felt a light head and slight dizziness. There was a solid plus two for a couple of hours. I paid careful attention for auditory oddities that I had noted before, but they were not there. In an earlier trial (with 20 milligrams) the radio had the sound of being located in the outdoors with the sounds coming through the wall and into the room where I was. I was at a neutral baseline at about seven hours. (with 35 mg) There was a quiet climb, but it was marred with some tummy unquiet, and an annoying persistence of diarrhea. I was very impressed with eyes-closed patterning, which seemed to do its own thing independently of the music. I was clearly up to a +++, but there was a feeling that as soon as it got there it started to go away again. There was no there, there. Yet there were a couple of touches of introspection, of seriousness which I had to respect. (with 40 mg) There were four of us, and the entry was individual for each of us. Two of us were nauseous. One volunteered a statement, almost a confession, of too much food and drink in the immediate past. One of us needed his cigarette right now, and then he saw that he was killing himself, and he swore off. DonUt know if it will last, however. At the two and a half hour point there is a consensus that this has gone its route and will lose its impact, so three of us decided to supplement on 2C-T-2. Six milligrams proves to be a little light so, some four hours later, we each took another six milligrams. Excellent. In a while we discoved that we were very hungry, and food tasted marvelous. Headaches acknowledged in the early evening, but the extension from T-13 to T-2 seemed to be absolutely correct. And as of the next day, the non-smoker was still a non-smoker. EXTENSIONS AND COMMENTARY: Most of the synthetic adventures of putting a basic something aways out from the benzene ring, at the four-position, have involved subtle things such as unsaturated bonds or three-membered rings. This was the first try with the actual use of a different atom (an oxygen). What about other heteroatoms such as sulfur or nitrogen or silicon or phosphorus, or some-such? The sulfur counterpart of 2C-T-13 was named 2C-T-14, and was immediately launched. The reaction of 2,5-dimethoxythiophenol and KOH with 2-methyl-thioethyl chloride in hot MeOH gave 2,5-dimethoxyphenyl 2-methylthioethyl sulfide as a white oil (boiling point of 140-160 !C at 0.3 mm/Hg). This underwent a normal Vilsmeier reaction (phosphorous oxychloride and N-methylformanilide) to give 2,5-dimethoxy-4-(2-methylthioethylthio)benzaldehyde with a melting point of 64-64.5 !C from MeOH. This, in nitromethane containing a little ammonium acetate, was heated on the steam bath for 10 hours and worked up to give an excellent yield of 2,5-dimethoxy-4-(2-methylthioethylthio))-'-nitrostyrene as garish orange-red RLas VegasS colored crystals from acetonitrile, with a melting point of 126-127 !C. And as of the moment, this is sitting on the shelf waiting to be reduced to the target compound 2,5-dimethoxy-4-(2-methylthioethylthio)phenethylamine hydrochloride, or 2C-T-14. Will it be active? I rather suspect that it will be, and IUll bet it will be longer-lived than the oxygen model, 2C-T-13. #47 2C-T-15; SESQUI; 2,5-DIMETHOXY-4-CYCLOPROPYLTHIOPHENETHYLAMINE SYNTHESIS: To a solution of 3.3 g of KOH pellets in 150 mL hot MeOH, there was added 10 g 2,5-dimethoxythiophenol (see recipe for 2C-T-2 for its preparation) followed by 10 g 1-bromo-3-chloropropane. The reaction was exothermic, and immediately deposited white solids of KCl. The reaction mixture was warmed for a few min on the steam bath, and then quenched in H2O. The basic reaction mixture was extracted with 3x75 mL CH2Cl2. The pooled extracts were stripped of solvent under vacuum. The residual oil was distilled at 145-155 !C at 0.2 mm/Hg to give 16.5 g of 2,5-dimethoxyphenyl 3-chloropropyl sulfide as a clear, colorless oil. A solution of the lithium amide of 2,2,6,6-tetramethylpiperidine was prepared by the addition of 20 mL of 2.6 M butyllithium in hexane to a well stirred hexane solution of the piperidine in 100 mL hexane, under an atmosphere of He. The reaction was exothermic, formed a white solid precipitate, and was allowed to continue stirring for a few min. There was then added 6.5 g 2,5-dimethoxphenyl 3-chloropropyl sulfide, and a strongly exothermic reaction ensued. This was stirred for 30 min and then poured into dilute H2SO4 (the progress of the reaction must be followed by TLC, silica gel plates, CH2Cl2:petroleum ether 50:50 to determine when it is done; in one run over 2 h were required for completion of the reaction). The organic phase was separated, and the aqueous phase extracted with 3x75 mL EtOAc. The combined organic phases were washed first with dilute NaOH, then with dilute HCl, then the solvents were removed under vacuum. The residue was distilled to provide 2,5-dimethoxyphenyl cyclopropyl sulfide as a pale yellow liquid that boiled at 100-115 !C at 0.1 mm/Hg. The use of other bases to achieve this cyclization were less successful. Incomplete cyclization resulted from the use of lithium diisopropyl amide and, if the conditions were made more vigorous, there was dehydrohalogenation to the allyl sulfide. An unexpected difficulty was that the allyl sulfide (from elimination) and the 3-chloropropyl sulfide (starting material) behaved in an identical manner on TLC analysis. They were easily separated, however, by GC analysis. A completely different approach to the synthesis of this sulfide was explored through the reaction of cyclopropyllithium with an aromatic disulfide, thus avoiding the base-promoted cyclization step. A solution of 2.6 g di-(2,5-dimethoxyphenyl)disulfide (from 2,5-dimethoxythiophenol and hydrogen peroxide, bp 220-230 !C at 0.3 mm/Hg) was made in anhydrous Et2O, and well stirred. In a separate flask, under an atmosphere of He, 4 mL of 2.6 M butyllithium was added to a solution of 1.2 g cyclopropyl bromide in 20 mL anhydrous Et2O. This mildly exothermic combination turned a bit cloudy, was stirred for 1 h, then trans-ferred with an air-tight syringe to the above-described Et2O solution of the aromatic disulfide. A heavy precipitate formed, and stirring was continued for an additional 0.5 h. The reaction mixture was then poured into H2O, the layers separated, and the aqueous phase extracted with CH2Cl2. The extracts were pooled, washed with dilute aqueous KOH, and the solvents removed under vacuum. Distillation gave 0.7 g of 2,5-dimethoxyphenyl cyclopropyl sulfide with identical gas chromatographic behavior to the sample prepared by the cyclization of the chloropropylthio compound. A mixture of 7.2 g POCl3 and 6.7 g N-methylformanilide was heated on the steam bath until it was claret red. To this there was added 4.5 g of 2,5-di-methoxyphenyl cyclopropyl sulfide, and the exothermic combination heated on the steam bath for about 5 min. The deep red, bubbling reaction mixture was added to 150 mL H2O and stirred until all oils had been converted into loose solids. These were then removed by filtration, washed with H2O, and sucked as dry as possible. They were dissolved in boiling MeOH which, after cooling in an ice-bath, deposited yellow crystals of 2,5-dimethoxy-4-(cyclopropylthio)benzaldehyde that weighed 3.43 g after air drying, and had a mp of 97-99 !C. Anal. (C12H14O3S) C,H. To a solution of 3.0 g 2,5-dimethoxy-4-(cyclopropylthio)benzaldehyde in 40 g of nitromethane there was added 0.2 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 3 h. The excess nitromethane was removed under vacuum yielding 3.4 g orange crystals. These were recrystallized from 150 mL boiling IPA containing a little toluene. After cooling, filtering, and air drying there were obtained 2.75 g of 2,5-dimethoxy-4-cyclopropylthio-'-nitro-styrene as pumpkin-colored crystals with a mp of 159-160 !C. Anal. (C13H15NO4S) C,H. A solution of LAH (40 mL of a 1 M. solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 1.05 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 2.5 g 2,5-dimethoxy-4-cyclopropylthio-'-nitrostyrene in 40 mL anhydrous THF over the course of 15 min. There was an immediate loss of color. After a few min further stirring, the temperature was brought up to a gentle reflux on the steam bath and held there for 2 h. After recooling, there was added IPA (to destroy the excess hydride) followed by sufficent 15% NaOH to give a white granular character to the oxides, and to assure that the reaction mixture was basic. The reaction mixture was filtered, and the filter cake washed with THF. The filtrate and washes were stripped of solvent under vacuum providing a yellow oil that was treated with dilute H2SO4. This produced a flocculant white solid, apparently the sulfate salt of the product. This was washed with 4x75 mL CH2Cl2 which removed most of the yellow color. The aqueous phase was made basic with aqueous NaOH and extracted with 3x75 mL CH2Cl2. Removal of the solvent under vacuum gave a light yellow colored oil that was distilled at 0.3 mm/Hg. The fraction boiling at 140-150 !C was a colorless, viscous oil that weighed 1.97 g. This was dissolved in a few mL IPA, and neut-ralized with concentrated HCl forming immediate cottage cheese-like crystals of the hydrochloride salt. This was diluted by suspension in anhydrous Et2O, removed by filtration, and air dried to give 1.94 g of 2,5-dimethoxy-4-cyclopropylthiophenethylamine hydrochloride (2C- T-15) that had a mp of 203-5-204.5 !C. Anal. (C13H20ClNO2S) C,H. DOSAGE: greater than 30 mg. DURATION: several hours. QUALITATIVE COMMENTS: (at 30 mg) I was somewhere between a threshold and a plus one for several hours, and appeared to be quite talkative in the evening. EXTENSIONS AND COMMENTARY: The commonly used name for 2C-T-15, during its synthesis, was SESQUI. The general name for a 15-carbon terpene is sesquiterpene, from the Latin prefix for one and a half. The active level of 2C-T-15 is not known. The highest level yet tried was 30 milligrams orally, and there had been threshold reports pretty regularly all the way up from 6 milligrams. But no definite activity yet. This compound is isosteric with the isopropyl group as seen in the analogous compound 2C-T-4 (the three carbons are in exactly the same positions, only the electrons are located differently) and it is a little surprising that the potency appears to be considerably less. Just over 20 milligrams of the latter compound was overwhelmingly psychedelic. The entire mini-project of hanging cyclic things onto the sulfur atom was an interesting problem. This is the three carbon ring. The six carbon ring (the cyclohexyl homologue) was discussed as 2C-T-5 in the recipe for of ALEPH-2. The cyclobutyl and cyclopentyl homologs were assigned the names of 2C-T-18 and 2C-T-23, respectively, and their preparations taken as far as the nitrostyrene and the aldehyde stages, respectively, before the project ran out of steam. Towards the cyclobutyl homologue, a solution of 2,5-dimethoxythiophenol and cyclobutyl bromide in DMSO containing anhydrous potassium carbonate was stirred for several hours at room temperature and yielded 2,5-dimethoxyphenyl cyclobutyl sulfide as a white oil that boiled at 135-140 !C at 0.3 mm/Hg. Anal. (C12H16O2S) C,H. This was brought to react with a mixture of phosphorus oxy-chloride and N-methylformanilide producing 2,5-dimethoxy-4-(cyclobutylthio)benzaldehyde that had a melting point of 108-109.5 !C from MeOH. Anal. (C13H16O3S) C,H. Coupling with nitromethane in the presence of ammonium acetate produced 2,5-dimethoxy-4-cyclobutylthio-'-nitrostyrene as lustrous orange crystals from boiling acetonitrile, melting point 160-161 !C. Anal, (C14H17NO4S) C,H. This will some day be reduced to 2,5-dimethoxy-4-cyclobutylthiophenethylamine hydrochloride, 2C-T-18. Towards the cyclopentyl homologue, a solution of 2,5-dimethoxythiophenol and cyclopentyl bromide in DMSO containing anhydrous potassium carbonate was stirred for several hours at room temperature and yielded 2,5-dimethoxyphenyl cyclopentyl sulfide as a white oil that boiled at 135-145 !C at 0.3 mm/Hg. This was brought to react with a mixture of phosphorus oxychloride and N-methylformanilide producing 2,5-dimethoxy-4-(cyclopentylthio)benzaldehyde as yellow crystals from MeOH. This will some day be converted to the nitrostyrene and then reduced to 2,5-dimethoxy-4-cyclopentylthiophenethylamine hydrochloride, 2C-T-23. #48 2C-T-17; NIMITZ; 2,5-DIMETHOXY-4-(s)-BUTYLTHIOPHENETHYLAMINE SYNTHESIS: To a solution of 2.6 g of KOH pellets in 50 mL hot MeOH, there was added a mixture of 6.8 g 2,5-dimethoxythiophenol (see under 2C-T-2 for its preparation) and 5.8 g (s)-butyl bromide. The reaction was exothermic, with the deposition of white solids. This was heated on the steam bath for a few h, the solvent removed under vacuum, and the resulting solids dissolved in 250 mL H2O. Additional aqueous NaOH was added to bring universal pH paper to a full blue color. This was extracted with 3x40 mL CH2Cl2, the extracts pooled, and the solvent removed under vacuum. The residue was 2,5-dimethoxyphenyl (s)-butyl sulfide which was a pale yellow oil, weighing 10.12 g. It was sufficiently pure for use in the next reaction without a distillation step. A mixture of 15.1 g POCl3 and 14.1 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 9.4 g of 2,5-dimethoxyphenyl (s)-butyl sulfide, and the mixture heated for 35 min on the steam bath. This was then added to 200 mL of well-stirred warm H2O (pre-heated to 55 !C) and the stirring continued until the oily phase had completely solidified (about 15 min). These light brown solids were removed by filtration, and washed with additional H2O. After sucking as dry as possible, these solids (12.14 g wet) were ground under an equal weight of MeOH which produced a yellowish crystalline solid with a mp of 76-81 !C. Recrystallization of a 0.4 g sample from an equal weight of boiling MeOH provided 0.27 g of 2,5-dimethoxy-4-(s-butylthio)benzaldehyde as a pale cream-colored crystalline material with a mp of 86-87 !C. To a solution of 8.0 g of the crude 2,5-dimethoxy-4-(s-butylthio)benzaldehyde in 40 g of nitromethane there was added 0.38 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 1 h. The reddish colored solution was decanted from some insoluble tan material and the excess nitromethane removed under vacuum. The heavy red oil that remained was diluted with an equal volume of boiling MeOH, and allowed to return to room temperature. The orange-colored crystals that slowly formed were removed by filtration and, after air drying, weighted 6.24 g. This was again recrystallized from an equal volume of MeOH, yielding 2,5-dimethoxy-4-(s-butylthio)-'-nitrostyrene as yellow, somewhat beady crystals that weighed (when dry) 3.50 g and which had a mp of 62-65 !C. A small portion of this fraction was crystallized yet again from MeOH to provide an analytical sample that was yellow-orange in color, and had an mp of 68-69 !C. Anal. (C13H17NO4S) C,H. A solution of LAH (120 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 3.3 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 8.83 g 2,5-dimethoxy-4-(s-butylthio)-'-nitrostyrene in 80 mL anhydrous THF dropwise over the course of 2 h. After a few min further stirring, the temperature was brought up to a gentle reflux on the steam bath, and then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of 18 mL IPA followed first by 5 mL of 15% NaOH and then by 15 mL of H2O. The reaction mixture was filtered, and the filter cake washed with THF. The filtrate and washing were combined and stripped of solvent under vacuum providing about 8.5 g of a pale amber oil. Without any further purification, this was distilled at 135-150 !C at 0.4 mm/Hg to give 6.12 g of a clear white oil. This was dissolved in 30 mL IPA, and neutralized with 2.1 mL of concentrated HCl forming crystals immediately. Another 10 mL of IPA was added to allow the solids to be finely dispersed, and then about 100 mL of anhydrous Et2O were added. The solids were removed by filtration, Et2O washed, and air dried to constant weight. The product, 2,5-dimethoxy-4-(s)-butylthiophenethylamine hydrochloride (2C-T-17) was obtained as spectacular white crystals, weighing 5.67 g. DOSAGE: 60 - 100 mg. DURATION: 10 - 15 h. QUALITATIVE COMMENTS: (with 60 mg) This material took fully three hours to get into its maximum effect. I never was at a +++, quite, and I am not sure why it is really active, but I know it is. There does not seem to be any interference with my concentration or mental coordination, but I wouldnUt want to drive right now. Good appetite in the evening, for a Chicago-style pizza, and there was no Tomso effects (the rekindling of a psychedelic effect with alcohol) with a glass of wine. An over-all good and instructive ++, no visuals, totally benign. There is no hesitation in doing it again some day. (with 100 mg) A small fragment hadnUt dissolved when I drank the solution, and it must have stuck to the back of my mouth, because it made a searing spot that burned for 5 minutes. The first central effects were noted at an hour. The plateau stretched from the 3rd to the 7th hour, then tapered off quite quickly. My sleep was fitful, with some hints of nervous sensitivity. I felt that there were some residuals even into the next morning. A truly heavy psychedelic, but with very few explicit sensual changes or unusual perceptions to justify that comment. Why is it heavy? It just is. This dosage is high enough. EXTENSIONS AND COMMENTARY: An interesting, and quite logical, habit that seems to always pop up when a lot of talk and energy become directed at a specific compound, is the habit of using a nickname for it. The Tweetios are an example, and in the 2C-T-X family I had mentioned the term SESQUI. Here, this compound was called NIMITZ, for the obvious reason that the major freeway from Oakland to San Jose, the Nimitz freeway, was also called State Highway 17. Its name has been changed to Interstate 880, and I guess it could now only be used as a reference point if efforts were being made for a 2C-T-880. The reason that 2C-T-17 is of special theoretic interest is that it is one of the very first of the active psychedelic compounds (along with 2C-G-5) to have a potential optically active center on the side of the ring away from the nitrogen atom. One of the oldest and best studied variants of the phenethylamine chain are the alpha-methyl homologues, the substituted amphetamines. Here there is an asymmetric carbon atom right next to the amine group, allowing the molecule to be prepared in either a right-hand way or a left-hand way. The RRS or the RSS isomer. And in the several studies that have looked at such isomers separately, it has always been the RRS isomer that has carried the psychedelic effects. This probably says something about the nitrogen end, the metabolic end, the RnorthS end of the receptor site that recognizes these compounds, and suggests that there is some intrinsic asymmetry in the area that binds near to the basic nitrogen atom. But very little is known of the receptor's RsouthS end, so to speak, the geometry of the area where the opposite end of the molecule has to fit. Here, with 2-C-17, there is a secondary butyl group, and this contains an asymmetric carbon atom. But now this center of asymmetry is clear across the benzene ring from the nitrogen, and should certainly be in some entirely new part of the receptor site. Why not make this compound with the RRS and the RSS forms in this new and unusual location? Why not, indeed! Why not call them the right-lane and the left lane of the Nimitz? Fortunately, both RRS and RSS secondary butyl alcohols were easily obtained, and the synthesis given above for the racemic compound was paralleled for each of these isomers, separately. Is there any chemistry that is different with the specific optical isomers from that which has been reported with the racemic? There certainly is for the first step, since the butyl alcohols rather than the butyl bromides must be used, and this first step must go by inversion, and it cannot be allowed any racemization (loss of the optical purity of the chiral center). The synthesis of 2C-T-17 RRS required starting with the RSS isomer of secondary butanol. The RSS 2-butanol in petroleum ether gave the lithium salt with butyllithium which was treated with tosyl chloride (freshly crystallized from naphtha, hexane washed, used in toluene solution) and the solvent was removed. The addition of 2,5-dimethoxythiophenol, anhydrous potassium carbonate, and DMF produced RSS 2,5-dimethoxyphenyl s-butyl sulfide. The conversion to RRS 2,5-dimethoxy-4-(s-butyl-thio)benzaldehyde (which melted at 78-79 !C compared to 86-87 !C for the racemic counterpart) and its conversion in turn to the nitrostyrene, RSS-2,5-dimethoxy-4-(s)-butylthio-'-nitrostyrene which melted at 70-71 !C compared to 68-69 !C for the racemic counterpart, followed the specific recipes above. The preparation of the intermediates to 2C-T-17 RSS follows the above precisely, but starting with RRS 2-butanol instead. And it is at these nitrostyrene stages that this project stands at the moment. It would be fascinating if one of the two optically active 2C-T-17Us carried all of the central activity, and the other, none of it. What is more likely is that the spectrum of effects will be teased apart, with one isomer responsible for some of them and the other isomer responsible for the others. Then, again, maybe the south end of the receptor site in the brain is totally symmetric, and the two optical antipodes will be indistinguishable. An incidental bit of trivia Q yet another bit of evidence that we are all totally asymmetric in our personal body chemistry. RRS and RSS secondary butanols smell different. The RRS has a subtle smell, which is rather fragrant . The RSS is stronger, hits the nasal passages harder, and reminds one of isopropanol more than does the RSS isomer. #49 2C-T-21; 2,5-DIMETHOXY-4-(2-FLUOROETHYLTHIO)PHENETHYLAMINE SYNTHESIS: To a solution of 6.9 g of KOH pellets in 100 mL hot MeOH, there was added 13.0 g 2,5-dimethoxythiophenol (see under 2C-T-2 for its preparation) followed by 9.6 g 2-fluoroethyl bromide. The reaction was exothermic, with the immediate deposition of white solids. This was allowed to stand for 2 h, added to 1 L H2O, and extracted with 3x75 mL CH2Cl2. The extracts were pooled and the solvent removed under vacuum. The residue was 2,5-dimethoxyphenyl 2-fluoroethyl sulfide which was a colorless oil and weighed 17.2 g. It was sufficiently pure for use in the next reaction without a distillation step. A mixture of 26.8 g POCl3 and 24.8 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 17.0 g of 2,5- dimethoxyphenyl 2-fluoroethyl sulfide, and the mixture heated an additional 25 min on the steam bath. This was then added to 1.5 L of well-stirred warm H2O (pre-heated to 55 !C) and the oily phase that formed solidified almost immediately. This brown sugar-like product was removed by filtration, and washed with additional H2O. After sucking as dry as possible, the residual solids (weighing 19.0 g wet) were dissolved in an equal weight of boiling MeOH which, after cooling in an ice-bath, deposited pale ivory colored crystals of 2,5-dimethoxy-4-(2-fluoroethylthio)benzaldehyde. This was air dried to constant weight, which was 15.1 g. To a solution of 15.0 g 2,5-dimethoxy-(2-fluoroethylthio)benzaldehyde in 75 mL nitromethane there was added 1.35 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 70 min (the progress of the reaction must be followed by continuous TLC monitoring). The clear deeply-colored solution was decanted from some insoluble material and the excess nitromethane removed under vacuum. There resulted 17.78 g of almost dry brick-red crystals which were dissolved in 110 mL boiling EtOAc. After cooling overnight in the refrigerator, the crystalline product was removed, washed with EtOAc, and air dried. There was obtained 14.33 g of 2,5-dimethoxy-4-(2-fluoroethylthio)-'-nitro-styrene as bright orange crystals. A solution of LAH (140 mL of a 1 M solution in THF) was cooled, under He, to 0 !C with an external ice bath. With good stirring there was added 3.7 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 8.9 g 2,5-dimethoxy-4-(2-fluoroethylthio)-'-nitrostyrene in 40 mL of hot anhydrous THF (a heat lamp was needed to keep the nitrostyrene in solution). As the nitrostyrene entered the hydride solution, there was an immediate loss of color. After 1 h stirring at room temperature, the temperature was brought up to a gentle reflux on the steam bath, then all was cooled again to 0 !C. The excess hydride was destroyed by the cautious addition of 15 mL IPA and the inorganic solids were made white and filterable by the addition of 15 ml 15% NaOH. The loose cottage-cheesy solids were removed by filtration, and washed with additional THF. The filtrate and washes were pooled and stripped of solvent under vacuum providing 7.39 g of a pale amber oil. This was dissolved in 600 mL dilute H2SO4, and washed with 3x50 mL CH2Cl2 (which removed the light yellow color). The aqueous phase was made strongly basic with 25% NaOH, extracted with 3x75 mL CH2Cl2 and, after pooling, the solvent was removed under vacuum leaving 4.91 g of product as an oil. This was distilled at 145-160 !C at 0.4 mm/Hg giving 3.91 g of a white oil. This was dissolved in 40 mL IPA and neutralized with 35 drops of concentrated HCl. The beautiful white solids that formed were removed by filtration, and washed with IPA. All were suspended in, and ground under, 40 mL anhydrous Et2O, refiltered and air dried. The final weight of 2,5-dimethoxy-4-(2-fluoroethylthio)phenethylamine hydrochloride (2C-T-21) was 4.07 g of glistening white crystals. DOSAGE 8 - 12 mg. DURATION: 7 - 10 h. QUALITATIVE COMMENTS: (with 6 mg) I noticed something undefined within five minutes which went away. Within 15 minutes I noticed a definite awareness of activity. There was a progressive increase in awareness of something happening over the next two hours with a plateau of perhaps an hour then occurring. The nature of the happening, as usual, was not clear. During the experience I was more talkative than I usually am. I seemed to be interacting with all others. There was no euphoria but, then, there was no body load or nausea, nor was there any nystagmus. I found a little mental confusion at the peak and there was some searching in my memory bank for the right chips at times. I lost the entire line of one of my conversations at one point during the plateau and had to ask what I was talking about. I tested my visual field on a painting and with sufficient concentration I could get the center part to wiggle a little. I didnUt try to observe anything with my eyes closed. I feel that there was something physical about the eyes. In the evening, after-images were quite intense, and the next day my eyes seemed tired or bothered. What can I say? The material was pleasant and I certainly got the feeling of being high but not getting too much out of it. There were no insights or Rah-hahs.S I wonder if periodic and frequent use (say twice a day) at the one or two milligram level would be a positive mood enhancer?S (with 8 mg) Comes on very gradually and slowly. Takes about an hour to feel. Reasonably intense in two hours, ++. Very pleasant material, enhancing communication, clear thinking, good feeling. There is a feeling of closeness; the bondedness with the group grows steadily during the day, reaching a highly rewarding level. For me a couple of firsts regarding food. I was hungry only two hours into it. I usually donUt want food 'til well down as I usually feel that it interferes with the experience. And, also, I nibbled constantly as I felt that there was nothing in my body. And I enjoyed it thoroughly, feeling only the warmth and energy, with no contrary developments. There was a nice feeling of inner strength and peace. (with 8 mg) It was very difficult to fix the times of ascent or descent. Some chilling during onset but not later. And there was some yawning and ear-popping. It is easy on the body, in no way threatening. This time I am very relaxed and somewhat lethargic; the visuals are not too pronounced. Excellent sleep. (with 10 mg) I find I can use it if I set my energy in a direction I really want to go in. Otherwise I can just be stoned and self-indulgent. Not out-of-body cosmic at all. But it's good material, an ally, not presenting hidden negatives. (with 12 mg) Well ... 12 milligrams is quite enough for a +3, which was established within the first hour and plateauUd by the end of the second. Body felt quite safe, again, but there was considerable push of energy. I did not feel par-ticularly interested in doing anything like writing and in fact preferred to watch television while rocking a bit on the couch, to ease the push. Mood was faintly grim, but not more than faintly. I noted something that I hadnUt seen before with this material: time slowing. The first two hours seemed to last a very long time. There was no anorexia. It wasnUt until 10 PM [fifth hour] that the idea of writing had any appeal at all. By then, I was still +3 but a lot more at ease. I wrote two letters and enjoyed the process. Sleep was fine. My mood next day was slightly introverted, not very spontaneous for a while. Late in the afternoon, it was a lot better. EXTENSIONS AND COMMENTARY: This is about as potent a phenethylamine as they come. There are a couple in the 2C-G family that are similar in potency, but they are much longer lived. The motivation for the use of the beta-fluoroethyl group can be seen under the discussion of DOEF, where there was an amalgamation of two lines of reasoning: the imitation of potent serotonin agonists with a need of including an atom (the fluorine) that is potentially labelable with a positron emitter. And the mass-18 isotope of fluorine, with a half-life of just under 2 hours, is ideal for many biological studies. In fact, much of the research work being carried out by the Nuclear Medicine group in Berkeley is based on the analogy between a halogen atom and a beta-fluoroethyl group. There are some similarities in pharmacology so that if there is a bromine or an iodo atom present in a drug, it is a fair guess that the corresponding beta-fluoroethyl would also be active. In a sense, the cute (and chemically impossible) idea of putting a bromo atom on the sulfur of the 2C-T family is nicely satisfied by using the beta-fluoroethyl group instead (which is chemically completely possible). A logical extension of 2C-T-21 is the three carbon amphetamine analogue which should be, by comparing structures and activities, a very potent and in-teresting material in its own rights. This would be 2,5-dimethoxy-4-(2-fluoroethylthio)amphetamine or, following the nomenclature used with the earlier members of this series, ALEPH-21. A solution of 2,5-dimethoxy-4-(2-fluoroethylthio)benzaldehyde (see earlier in this recipe) in nitroethane with ammonium acetate gave 1-(2,5-dimethoxy-4-(2-fluoroethylthio)phenyl)-2-nitropropene as yellow-orange crystals from MeOH with a melting point of 102-104 !C. And that is where the project now stands. It has not yet been reduced to the amine. This phenethylamine, 2C-T-21, was the last of the 2C-T's to be completed. A couple of other sulfur analogues have been given numbers, and have been started, but the syntheses are still at some intermediate state. The (n)-butyl compound, named 2C-T-19, has been taken to the nitrostyrene stage. Reaction between 2,5-dimethoxythiophenol and (n)-butylbromide with KOH gave 2,5-dimethoxyphenyl (n)-butyl sulfide as a colorless oil. This, with phosphorus oxychloride and N-methylformanilide, provided 2,5-dimethoxy-4-(n-butylthio)benzaldehyde as pale orange solids from MeOH, with a melting point of 78-79 !C. This, with nitromethane and ammonium acetate, gave 2,5-dimethoxy-4-(n-butylthio)-'-nitrostyrene, with a melting point of 133-134 !C from either IPA or acetonitrile. The 2,2,2-trifluoroethyl compound, which I have named 2C-T-22, has been taken to the benzaldehyde stage. Reaction between 2,5-dimethoxythiophenol and 2,2,2-trifluoroethyliodide with KOH gives 2,5-dimethoxyphenyl 2,2,2-trifluoroethyl sulfide as a very pale amber oil. This, with phosphorus oxychloride and N-methylformanilide provided 2,5-dimethoxy-4-(2,2,2-trifluoroethyl)benzaldehyde as crystals that proved to be exceedingly difficult to purify. Yellow solids can be obtained from several solvents, and they melt in the 70 !C area. The initially isolated fraction melted at 69-72 !C and showed three major spots by both TLC and GCMS. The largest GC peak was the correct product with a parent peak of 280 m/e, and cracking fragments at 154 and 234 m/e. A small sample was finally obtained from hexane with a melting point of 78-79 !C but I am not sure that even it is particularly pure. Not surprisingly, the reaction of this crude benz-aldehyde with nitromethane and ammonium acetate gave a nitrostyrene product that was a complex mixture. And there that project also rests. A couple of additional efforts warrant comment. The reaction between trifluoromethyliodide and 2,5-dimethoxythiophenol should have produced 2,5-dimethoxyphenyl trifluoromethyl sulfide, but it didnUt produce anything. And one more. What about a bare thio group at the 4-position in this 2C-T-family? Maybe this can be protected through everything as the disulfide, and be reduced at the last step! The disulfide, 2,5-dimethoxyphenyl disulfide (see under 2C-T-15) was aimed towards the needed bis-aldehyde with phosphorus oxychloride and N-methylformanilide, but all that came out of this were black oils and tars. This has also been abandoned for now. And it has just occurred to me that there is yet another effort that is certain-ly worth making, inspired by the observation that 2,2-difluoroethyl iodide is commercially available and not prohibitively expensive. It, with 2,5-dimethoxythiophenol, and following the obvious steps to the aldehyde, the nitrostyrene, and the final amine, would produce 2,5-dimethoxy-4-(2,2-difluoroethylthio)phenethylamine hydrochloride. It lies exactly half way between the highly potent 2C-T-21 (the mono-fluoro), and the yet to be finished 2C-T-22 (the trifluoro). Let's be weird, and call it 2C-T-21.5. I will wager mucho that it will be very potent. #50 4-D; 3,5-DIMETHOXY-4-TRIDEUTEROMETHOXY-PHENETHYLAMINE SYNTHESIS: To a solution of 34.0 g homosyringonitrile (3,5-dimethoxy-4-hydroxyphenylacetonitrile, see under ESCALINE for its preparation) in 350 mL acetone containing 0.5 g decyltriethylammonium iodide, there was added 25 g trideuteromethyl iodide followed by 50 g of finely powdered anhydrous K2CO3. This mixture was held at reflux on a steam bath for 12 h, added to 2 L of dilute HCl, and extracted with 3x100 mL of CH2Cl2. The extracts were washed with 5% NaOH, and the solvent removed under vacuum, yielding 28.0 g yellow solids. These were distilled at 135-150 !C at 0.5 mm/Hg providing 19.4 g 3,5-dimethoxy-4-trideuteromethoxyphenylacetonitrile which melted at 76.5-77.5 !C after crystallization from toluene, or 77-78 !C from methylcyclohexane/CHCl3 3:1. The mp of the proteo-reference compound, from toluene, was 77-78.5 !C. The OCD3 stretch in the infra-red occured at 2072 cm-1. A solution of 275 mL of 1.0 M LAH in THF was cooled under He to 0 !C and treated with 7.25 mL 100% H2SO4 added very slowly with vigorous stirring. A solution of 19.3 g 3,5-dimethoxy-4-trideuteromethoxyphenylacetonitrile in 200 mL anhydrous THF was added slowly, and following the addition stirring was continued for 20 min. The reaction mixture was brought to a reflux for 30 min on a steam bath, cooled again to 0 !C, and the excess hydride destroyed with 25 mL IPA. About 15 mL of 15% NaOH was required to convert the solids to a filterable white consistency. These were removed by filtration, the cake washed with IPA, the filtrates and washes were combined, and the solvent removed under vacuum leaving a white oil as residue. This was dissolved in 1.5 L dilute H2SO4, washed with 3x75 mL CH2Cl2, made basic with aqueous NaOH, and then extracted with 3x75 mL CH2Cl2. Removal of the solvent from these extracts under vacuum yielded 18.5 g of a colorless oil which was distilled at 120-150 !C at 0.5 mm/Hg to provide 13.5 g of a white oil. This was dissolved in 70 ml IPA and neutralized with concentrated HCl, producing spontaneous crystals. These were removed by filtration, washed first with IPA then with anhydrous Et2O. After air drying, the final yield of 3,5-dimethoxy-4-trideuteromethoxyphenethylamine hydrochloride (4-D) was 13.50 g. DOSAGE: 200 - 400 mg (as the sulfate salt); 178 - 356 mg (as the hydrochloride salt). DURATION: 12 h. QUALITATIVE COMMENTS: (with 275 mg) The onset was smooth and gradual. Within the hour, the slight queasiness I experienced (not as much as with mescaline) completely disappeared. Some visual enhancement, good energy, good communication. It was a very special day for me as I was in a good place pretty much the whole day, and able to communicate clearly without deeper feelings getting in the way. While most enjoyable, and at times remarkable fun, I did not experience the intensity I am familiar with, with mescaline. (with 300 mg) The taste was bitter to a moderate degree but faded fast. About 40 minutes later the first stirrings of pleasurable experience came on. It was very mild. Twenty minutes after that an unease of the stomach was apparent, and it stayed with me until I ate some crackers an hour or so later. I got no sharpened visual reactions and no physical instability at any time. I did feel a quickening of thought and verbal flow; again, this was mild and unlike my earlier mescaline patter. (with 350 mg) A rapid onset Q alert in 20 minutes. Climbed to a plus two in about one hour and stayed there. During the first two hours had a slight queasiness or pre-nausea, and cold hands and feet, but this all disappeared completely and I became very hungry during the whole latter half of the experience. I did not eat much at any one time, but did a lot of snacking and everything tasted good. Very pleasant after the plateau was reached. Pretty good visuals with eyes closed, but not as bright as 2C-B. Very little visuals with eyes open Q some movement and flow of objects Q pupils dilated. Spent most of the day lying down Q had no aversion to conversation but it felt good just to be still. I was in a funny place I canUt quite describe Q I was in an 'alert lassitude,' a state of 'interested detachment,' or a place of 'vibrating equanimity' or whatever. While trying to recapture the day, it seemed to me that it was a good day, but that nothing much had really transpired. However, upon reflection, I am startled to find that several important shifts took place. It was a day that allowed some peaceful gear-shifting in the mind. (with 400 mg) Not a great taste. Some type of awareness at approx. 20 minutes. Considerable nausea peaking at about 1 hr. Some nausea continued through the experience but became quite low. I enjoyed the color show considerably. Trees outside would change color in a wave-like manner. The book-covers upstairs would also change colors and become distorted. Brightly lighted items would undergo the same thing. Believed I could suppress the vision, but concentrating on something would cause it to easily undergo the color and visual changes. Evidently I had little problem following the conversation downstairs, but I remained somewhat quiet. Had an element of confusion that seemed to last for some 4 or 5 hours. Had no problems dropping off to sleep that evening. EXTENSIONS AND COMMENTARY: The effects of 4-D and '-D are similar to one-another, both as to dosage and effect. And with both, there is a close parallel to those reported from mescaline. It is reasonable to assume that the human body handles these materials in the same manner, although no metabolic studies have ever been published. A similar deuterium substitution pattern is of course completely feasible with TMA and related 3,4,5-trimethoxy-substituted analogues. Some studies have supported the idea that the ability to remove methyl groups from such aromatic ethers might be correlated to endogenous schizophrenia. It is possible to imagine that, in such individuals, the effects of substituting trideuteromethyl groups for normal methyl groups might result in psychopharmacological differences of action. Two reports exist that describe metabolic products of mescaline that have lost this methyl group on the 4-position oxygen. It is possible that these might be produced in abnormal quantities in mentally ill subjects. There are also similar reports of the 3-methoxyl group being demethylated in man. Here, studies with 3,5-D (3,5-bis-trideuteromethoxy-4-methoxyphenethylamine) might reveal some differences in quantitative responses in man. These are extremely minor metabolites, however. I suspect that more extensive studies will establish that 4-D, 3,5-D and '-D all have properties indistinguishable from one-another, at least in healthy subjects. #51 '-D; 3,4,5-TRIMETHOXY-','-DIDEUTEROPHENETHYLAMINE SYNTHESIS: To a solution of 13.6 g homosyringonitrile (see under ESCALINE for its preparation) in 150 mL acetone containing 200 mg decyltriethylammonium iodide and 30 g of finely powdered anhydrous K2CO3, there was added 20 g methyl iodide. The mixture was held at reflux for 18 h in a heating mantle with effective stirring. This was added to 1 L H2O, acidified with concentrated HCl, and extracted with 3x75 mL CH2Cl2. The extracts were pooled, washed with 2x100 mL 5% NaOH, once with dilute HCl, once with saturated brine, and the solvent was removed under vacuum. The pale yellow residue was distilled at 130-150 !C at 0.3 mm/Hg to yield 12.9 g of 3,4,5-trimethoxyphenylacetonitrile as an off-white solid. Upon crystallization from methylcyclohexane/CHCl3 it was white and had a mp of 77-78 !C. Attempts to prepare this compound by the theoretically appealing route from 3,4,5-trimethoxybenzaldehyde to N,N-dimethyl-3,4,5-tri-methoxybenzylamine (reductive amination with dimethylamine), to 3,4,5-trimethoxy-N,N,N-trimethylbenzylammonium iodide (methylation with methyl iodide), and then to 3,4,5- trimethoxyphenylacetonitrile (with some source of cyanide ion) gave excellent yields in the first two steps, and no product at all in the last step. A solution of 20.6 g of 3,4,5-trimethoxphenylacetonitrile in 70 g pyridine was treated with 15 mL 99+% D2O and held at reflux for 24 h. All volatiles were stripped first under vacuum and finally with a hard vacuum at room temperature in a Kugelrohr apparatus. The dark residue was treated again with another 30 mL pyridine and another 15 mL 99+% D2O. The flask was protected with a drying tube and held at reflux for another 24 h. Again, all volatiles were stripped, and the residue distilled at 110-130 !C at 0.25 mm/Hg to yield 16.77 g of an almost white solid. The GCMS verified this chemical to be 3,4,5-trimethoxy-','-dideuterophenylacetonitrile, with a parent peak at m/e 209 and no visible peak at m/e 207. A solution of 250 mL of 1 M LAH in THF was cooled under He to 0 !C and treated with 6.8 mL 100% H2SO4 added very slowly with vigorous stirring. A solution of 18.23 g 3,4,5-trimethoxy-','-dideuterophenyl-acetonitrile in 200 mL anhydrous THF was added slowly, and following the addition stirring was continued for 20 min. The reaction mixture was brought to a reflux for 30 min on a steam bath, cooled again to 0 !C, and the excess hydride destroyed with 15 mL IPA. About 10 mL of 15% NaOH was required to convert the solids to a filterable white consistency. These were removed by filtration, the cake washed with IPA, the filtrates and washes were combined, and the solvent removed under vacuum leaving 17 g of a white oil as residue. This was dissolved in 2 L dilute H2SO4, washed with 3x75 mL CH2Cl2, made basic with aqueous NaOH, and then extracted with 3x75 mL CH2Cl2. Removal of the solvent from these extracts under vacuum yielded 10.3 g of a colorless oil which was distilled at 120-130 !C at 0.3 mm/Hg to provide 9.2 g of a white oil. This was dissolved in 50 ml IPA and neutralized with concentrated HCl, producing spontaneous crystals. These were diluted with 50 mL anhydrous Et2O, removed by filtration, washed first with Et2O/IPA, and then with anhydrous Et2O. After air drying, the final yield of 3,4,5-trimethoxy-','-dideuterophenethylamine hydrochloride ('-D) was 10.0 g of white needles. DOSAGE: 200 - 400 mg (as the sulfate salt); 178 - 356 mg (as the hydrochloride salt). DURATION: 12 h. QUALITATIVE COMMENTS: (with 200 mg) The onset was very gradual and very gentle. At about an hour and a half I was rather out of my body (at least I wasnUt aware of my body, it felt so light). I was listening to Berlioz Requiem, and it took me to the highest realm. I was totally caught up in the magnificence of the music, of the genius it took to compose it, the love it took to complete it, and the devotion of the composer. I felt as though this music had been written for me. What came next is hard to remember because I was so taken with this experience which came only 1 1/2 hours after ingestion. I wondered what time it was and how come I was having a peak experience so soon, because this material was supposed to reach its peak after two hours. Well, now we can revise the records, heh? Incidentally this material is really good for interior work. It was a magnificent experience Q one of the best. (with 275 mg) I begin to feel it in 15 minutes, stomach getting squeamish. Looking up into the clouds, becoming absorbed in them, watching light grow in intensity, stomach feelings disappeared. Became totally absorbed by the music. Listening to Boito's Prologue to Mephistopheles Q exquisitely beautiful, dramatic. Lying on the couch, the music continuing, I was suddenly filled with enormous power. I realized that raw, male power was pouring through me as I had never before experienced it. I was wild, totally self satisfied, and completely oblivious of others and their needs. I wanted to strike out, to win, to conquer. I felt what conquerers have felt in the past, the unbridled passion to vanquish everything. I could see how such misguided power could lead nations to war. Wanting still more power, I was about to find out if God would grant me the power to destroy the world if I wished it, when I felt a gentle kiss on my brow. My wife had leaned over just in time to save the world. (with 275 mg) Never had I had such a magnificent appreciation of God. It was clear that if I minded my business and turned to Him to learn as I had been doing today, then I could continue to grow and learn in a most wonderful way. It became crystal clear to me that I didnUt have to help anybody or heal anybody, as everyone can turn directly to the source for their needs. An earth-shaking experience. (with 300 mg) I had extreme nausea, and vomited. This had a very hard impact on me, and I had to retreat with a paranoia that swept over me without warning. I lay down and let it sweep on, and through this came several very important insights. At least they were important to me. It was about the fourth hour before I could emerge from my retreat, and at that time I knew that I had answered some troublesome personal problems. It was a satisfactory day, but I probably shall not repeat it. (with 350 mg) Strong body awareness started within 15 minutes. Visual activity started within half an hour. Visuals were typical kinds, but seemed to arrive earlier. A strong experience of pleasantness started and continued throughout the experience. I tended to internalize to some extent. Ended on a water bed at maybe an hour and a half, pulled covers over me, and went inward with considerable visuals but not much insight. I felt good about where I was. I would not mind being there again, so something was going well. I am not sure how long this continued. The visuals decreased somewhere around the 5th or 6th hour. After 8 or 9 hours, activity considerably decreased. I felt quite clear and reasonably centered. Would I do this again? The answer is yes. (with 500 mg) I consumed the material over a period of twenty minutes, and at the 1 hour 45 minute point, havenUt had any nausea, but I am still careful not to bounce around. Am absolutely grounded even though I am completely into the experience. No more that state in which it is possible to seriously consider trying to rise two inches above the floor and skim, as I do so expertly in dreams. As a matter of fact I havenUt had those dreams for some time now. This material doesnUt allow the straddling of realities as does ordinary mescaline. I know where my realities are, and reality is, basically, where my center is. Thus I am grounded in the physical reality even when the doors are open to non-physical levels. EXTENSIONS AND COMMENTARY: The 4-D and the '-D are two of five obvious deuterium isomer derivatives of mescaline. The three remaining are: (1) 3,5-D (4-methoxy-3,5-bis-trideuteromethoxyphenethylamine); (2) 2,6-D (2,6-di-deutero-3,4,5-trimethoxyphenethylamine); and (3) a-D (a.a-dideutero-3,4,5-tri-methoxyphenethylamine). I fully expect both 3,5-D and 2,6-D to be indistinguishable from mescaline in effect, since it is known that not much metabolism takes place in man at these locations of the molecule. The last compound, a-D, could be quite a different matter. The principal metabolite of mescaline is 3,4,5-trimethoxyphenylacetic acid, and this product requires enzymatic attack at the exact position where the deuteriums will be located. To the extent that they are harder to remove (come off more slowly or to a lesser degree), to that extent the molecule will be more potent in man, and the dosage required for effects will be less. The compound will be easily made by the reduction of 3,4,5-trimethoxyphenylacetonitrile with lithium aluminum deuteride. And if there is a believable difference between a-D and mescaline, it will be necessary to synthesize each of the two optically active a-mono-deutero analogs. That will be quite a challenge. Some years ago I performed a fascinating series of experiments with another isotopically labeled mescaline derivative. This was '-14C labeled material, which I self-administered on three occasions, at three different levels. One dosage was with 350 milligrams, a second a few weeks later was with 4 milligrams, and a third was a few weeks later yet, with about 60 micrograms. In each case, exactly the same absolute quantity of radioactivity was administered, so the metabolic distribution was equally visible. Only the weight dosage was different. Urinary analysis was run for each experiment for the presence of unchanged mescaline, and for the primary metabolite, 3,4,5-trimethoxyphenylacetic acid. The smaller the dosage, the proportionately larger amount of mescaline was oxidized to the inactive acetic acid, and the smaller amount was excreted in an unchanged state. It seemed to me that there might be a finite capacity of the body to oxidatively deaminate mescaline, and at larger and larger dosages, this capacity became increasingly depleted. Perhaps this is why mescaline requires such a large dosage to be effective in man. #52 DESOXY; 3,5-DIMETHOXY-4-METHYLPHENETHYLAMINE SYNTHESIS: To a well-stirred solution of 31 g 2,6-dimethoxytoluene in 200 mL CH2Cl2 there was added 11 mL elemental bromine, a portion at a time. There was a copious evolution of HBr and the color gradually faded from deep red to straw. The reaction mixture was poured into 500 mL H2O, and the organic layer separated, washed first with dillute NaOH and finally with dilute HCl. The solvent was removed under vacuum, and the residue distilled at 85-90 !C at 0.4 mm/Hg to provide 44 g of 3-bromo-2,6-dimethoxytoluene as a white oil. A well-stirred solution of 42 mL diisopropylamine in 100 mL petroleum ether was placed in a He atmosphere and cooled to 0 !C with an external ice-water bath. There was then added 120 mL of a 2.5 M solution of n-butyllithium in hexane, producing a clear but viscous solution of the lithium amide. Maintaining this temperature, there was added 100 mL of anhydrous THF, followed by 10 mL dry CH3CN, which produced an immediate white precipitate. A solution of 23 g of 3-bromo-2,6-dimethoxytoluene in 75 mL anhydrous THF was then added which produced a light red color. The reaction mixture was allowed to come to room temperature. The color became progressively darkened, eventually becoming a deep red-brown. After 0.5 h, the reaction mixture was poured into 500 mL of dilute H2SO4, the layers were separated, and the aqueous layer extracted with 2x75 mL CH2Cl2. The organics were combined, the solvent removed under vacuum, and the residue distilled. Discarding a first fraction, the cut boiling at 125-165 !C at 0.3 mm/Hg was collected. This light yellow fraction spontaneously crystallized and weighed 11.0 g. Trituration under 20 mL petroleum ether provided 1.72 g of 3,5-dimethoxy-4-methylphenylacetonitrile as a yellowish solid. A solution of LAH in anhydrous THF under nitrogen (20 mL of a 1.0 M solution) was cooled to 0 !C and vigorously stirred. There was added, dropwise, 0.54 mL 100% H2SO4, followed by 1.5 g 3,5-dimethoxy-4-methylphenylacetonitrile as a solid. The reaction mixture was stirred at 0 !C for a few min, then brought to room temperature for 1 h, and finally to a reflux on the steam bath for 30 min. After cooling back to 0 !C there was added IPA until no more hydrogen was evolved, followed by sufficient 15% NaOH to produce a granular texture. The white solids were removed by filtration, and washed with THF. The filtrate and washes were stripped of solvent under vacuum, the residue added to 150 mL dilute H2SO4 and washed with 2x50 mL CH2Cl2. The aqueous phase was made basic with 25% NaOH, and extracted with 3x100 mL CH2Cl2. These extracts were pooled, the solvent removed under vacuum, and the residue distilled at 110-120 !C at 0.45 mm/Hg to give a colorless viscous oil. This was dissolved in 10 mL of IPA, neutralized with 10 drops of concentrated HCl and diluted with 20 mL anhydrous Et2O. The product was removed by filtration, washed with Et2O, and air dried to give 0.55 g 3,5-dimethoxy-4-methylphenethylamine (DESOXY) as white crystals. DOSAGE: 40 - 120 mg. DURATION: 6 - 8 h. QUALITATIVE COMMENTS: (with 40 mg) Initially I felt very chilled, so I lay down under a blanket. Eyes-closed imagery became very dream-like and my general state was felt as having lost my center. Also, not much in touch with feelings, sense of strangeness, almost alien view of the world. Not through recog-nizable eyes. Neither pleasant nor unpleasant, just strange. Was able to drift into sleep very easily, or sleep-like trance state, with disconnected, far-out imagery. After 3 hours the nausea was gone, I was able to get up and explore. A little food went down well. No drive, no strong focus in any direction. Feel this was a quite fascinating experience. Completely down by six hours. Would go a bit slowly because of slight hints of neurological sensitivity Q the instant chilling and a tendency to dart on going to sleep. The nervous system does not feel over-exposed, but all of a sudden there will be a millisecond of auditory hallucination, or an out-of-the-blue startle. So take it easy going up.S [Some 24 hours after this experiment had been completed, and a normal baseline re-established, a complex and psycho-logically disruptive syndrome occurred, that lasted for the better part of a week. The temporal juxtaposition between the use of desoxy and the subsequent Rspiritual crisisS initially suggested some possible connection, but in retrospect the events seem to be unrelated]. (with 40 mg) I have offered to be a control on an experiment where there had been a close relationship between a trial with desoxy and what might have been a psychotic break, or some kind of so-called spiritual emergency. These two events lay within a day of one another. I was aware of my 40 milligram dosage at about three-quarters of an hour into the experiment, and felt that there was no more in-tensification at the two-hour point. At that time I felt distinctly spaced but with a very good feeling, and I could see no reason not to increase the dosage at some future time. There was a good and mellow mood, and enjoyment in escapist reading. The only physical oddity that I noted was that there had been no urge to urinate, and only a small amount of quite concentrated urine was passed rather late in the experiment. I was at baseline at the fifth hour, and there was nothing unusual at any time during the following week. (with 100 mg) The stuff has a sweet taste! There was a slight heart-push in the early awareness period, with a pulse up to 100 and a feeling of pressure in the chest. There were no apparent visual enhancements, but the eyes-closed imagery to music was noteworthy. Thinking skills and conversation seemed to be fully under control, if not enhanced. There was none of the colorful psychedelic world of mescaline, but this might be just around the corner; perhaps with a larger dose. This is a comfortable in-between level. Sleep was not possible at the sixth hour, but two hours later, it was easy and very restful. There was no negative price to pay the next day. EXTENSIONS AND COMMENTARY: All substituents that are involved with the several drugs being discussed in this writing are really things that are stuck like warts on the benzene ring that is central to every phenethylamine. Some of these warts are things attached with a oxygen atom; there are some of these in every single compound in this story. No oxygen atom, no psychedelic effect. Without them, one has stimulants or, more frequently, no effects at all. But the removal of an oxygen atom (in those cases where there is more than one) can radically change the nature of the effects seen. This is the exact meaning of the term Rdesoxy.S RDesS, without, and RoxyS, the oxygen. Since this drug is simply the structure of mescaline with the oxygen at the 4-position plucked out of the picture, the first impulse was to abbreviate this compound as DOM for des-oxymescaline. However, a long, long time ago, in a universe far, far away, a compound was synthesized that had a methoxy group replaced by a methyl, and it was already named DOM. This was the first of the STP analogs, and the initials stood for desoxy (DO, losing an oxygen) and methyl (M, having it replaced with a methyl group). These are two different worlds. One M stands for Mescaline, and the other M stands for Methyl. Let's call it 4-desoxymescaline, or simply DESOXY, and be exact. This drug is a prime example of a pharmacological challenge directed to the metabolic attack at the 4-position as a mechanism for the expression of biological activity. A methoxy group there would allow easy removal of the methyl group from the oxygen by some demethylation process, but a bare methyl group there cannot be removed by any simple process. It must be removed by a very difficult oxidation. This is not the first time that oxygen atoms have been removed from the mescaline molecule. Both the 3,5-dideoxymescaline (3,5-dimethyl-4-methoxyphenethylamine) and 3,4,5-trideoxymescaline (also called desoxymescaline in the literature, but really tri-desoxymescaline or 3,4,5-trimethylphenethylamine) have been studied in the cat, and have shown extraordinary pharmacological profiles of CNS action. The trimethyl compound showed behavior that was interpreted as being intense mental turmoil, accompanied by a startling rise in body temperature. The significance is hard to determine, in that LSD gave similar responses in the cat, but mescaline was without effects at all. No human studies have been made on these compounds, just animal studies. But they might prove upon trial in man to be most revealing. They would have to be performed with exceptional care. The 3-carbon chain amphetamines that correspond to these mescaline look-alikes with one or more methoxy groups replaced with methyl groups, are largely untested and would require independent and novel syntheses. The 3,4,5-trimethylamphetamine is known, and is known to be very hard on experimental cats. A mescaline analogue with a bromo atom in place of the 4-methoxyl group is an analogue of mescaline in exactly the same way that DOB (a very potent am-phetamine) is an analog of TMA-2 (the original trisubstituted amphetamine). This analogue, 3,5-dimethoxy-4-bromoamphetamine, has been found to be a most effective serotonin agonist, and it is a possibility that it could be a most potent phenethylamine. But, as of the present time, it has never been assayed in man. #53 2,4-DMA; 2,4-DIMETHOXYAMPHETAMINE SYNTHESIS: To a solution of 10 g 2,4-dimethoxybenzaldehyde in 50 mL nitroethane there was added 0.5 g anhydrous ammonium acetate, and the mixture was heated on the steam bath for 2 h. The excess solvent/reagent was removed under vacuum, and the residue oil dissolved in 25 mL boiling MeOH. On cooling, this deposited yellow crystals of 1-(2,4-dimethoxyphenyl)-2-nitropropene that, after filtering, MeOH washing, and air drying, weighed 10.2 g and had a mp of 78-79 !C. A magnetically stirred suspension of 6.0 g LAH in 300 mL anhydrous Et2O was brought up to a gentle reflux under a He atmosphere. A total of 8.5 g 1-(2,4-dimethoxyphenyl)-2-nitropropene was introduced into the reaction mixture by allowing the condensed Et2O to leach it from a modified Soxhlet condenser. After the addition was complete, the reaction was held at reflux for an additional 24 h. After cooling with an external ice bath, the excess hydride was destroyed by the cautious addition of H2O. When the exothermic reaction had subsided, there was added 500 mL H2O, 150 g potassium sodium tartrate, and sufficient base to bring the pH above 9. The phases were separated, the organic phase dried over anhydrous MgSO4, the drying agent removed by filtration, and the clear filtrate then saturated with anhydrous HCl gas to produce white crystals of 2,4-dimethoxyamphetamine hydrochloride (2,4-DMA) with a mp of 146-147 !C. DOSAGE: greater than 60 mg. DURATION: short. QUALITATIVE COMMENTS: (with 60 mg) This is definitely threshold, or even a bit more. There is a lot of amphetamine-like component, and a certain blush of euphoria. There is also a diffusion of association, so it's more than just amphetamine, no question about it. At the three-hour point, it is definitely quieting down. EXTENSIONS AND COMMENTARY: What can one say as to the active dosage of 2,4-DMA? Nothing. What can one say as to the duration? Probably short. The 60 milligram report given above is the highest level that I personally know of having been tried in man, and there is no hint as to what might be found at a fully active dose, or just where that dose might be. It might be fully speedy. It might be fully psychedelic. It might give a cardiovascular push that would be scary. Studies of 2,4-DMA on vascular strips (associated with serotonin action) were not impressive in comparison with structurally related psychedelics, and it seems as if its action might involve norepinephrine release. It is a reasonable guess that there would be cardio-vascular activity at higher levels. But it will only be with human trials, someday, that the answer will be known for sure. The meta-orientation of the two methoxyl groups does, however, greatly increase the susceptibility of the aromatic ring to electrophilic attack. This is one of the three possible meta-dimethoxy substituted amphetamines, and it is the best studied one in the pursuit of potential radio-halogen substituted brain blood-flow agents. This strategy is discussed under IDNNA; the other two meta-compounds are discussed under 3,4-DMA. The homologues of 2,4-DMA that were iodinated (or occasionally fluor-inated) were mono- or di-alkylated on the nitrogen, and the precursor that was common to all was the corresponding acetone. The above nitrostyrene, 1-(2,4-dimethoxyphenyl)-2-nitropropene, was reduced in acetic acid with elemental iron, and the base-washed extracts stripped of solvent and distilled (125-145 !C at 0.5 mm/Hg) to give 2,4-dimethoxyphenylacetone as a water-white oil. The principal reductive amination product of this, the one that was most thoroughly explored with various halogenation schemes, was obtained by the reaction of 2,4-dimethoxyphenylacetone with dimethylamine and sodium cyanoborohydride. This product, 2,4-dimethoxy-N,N-dimethylamphetamine or 2,4-DNNA, distilled at 105-115 !C at 0.4 mm/Hg and formed a perchlorate salt that melted at 98-98.5 !C. This could be iodinated with the radio-iodide anion, when oxidized with chloramine-T in buffered sulfuric acid, to give the iodinated analogue (2,4-dimethoxy-N,N-dimethyl-5-iodoamphetamine) in an excellent yield. Radio-fluorination with acetyl hypofluorite gave the 5-fluoroanalogue (2,4-dimethoxy-N,N-dimethyl-5-fluoroamphetamine) in an acceptable yield. Both compounds went into a rat's brain to a pretty good extent, but both of them washed out too rapidly to be clinically interesting. A large family of other N-substituted homologues of 2,4-DMA were similarly prepared from the above ketone and sodium cyanoborohydride. Methylamine, ethylamine, propylamine, isopropylamine and hexylamine gave the corresponding N-alkyl homologues. The N,N-diethyl homologue was made from the primary amine, 2,4-DMA itself, with acetaldehyde and sodium cyanoborohydride but the product, N,N-diethyl-2,4-dimethoxyamphetamine, could not be converted into a crystalline hydrochloride salt. Yet another variation on these structures was launched, again with the design of making radio-iodination targets which are not psychedelic and thus might be useful clinically. In this variation, the nitrogen atom substitution pattern was held constant, with two methyl groups, as were the ring locations of the two oxygen atoms. But the identities of the alkyl groups on these oxygen atoms were varied. The synthetic procedure followed was to make the appropriate 2,4-dialkoxybenzaldehyde, convert it to the nitrostyrene with nitroethane, reduce this to the phenylacetone with elemental iron, and then reductively aminate this ketone with dimethylamine. Following this reaction scheme, five amphetamine homologues of 2,4-DMA were made, three with the 4-methoxy group maintained but the 2-position extended, and two with both groups extended symmetrically. These are: (1) N,N-dimethyl-2-ethoxy-4-methoxyamphetamine; (2) 2-(n)-butyloxy-N,N-dimethyl-4-methoxy-amphetamine; (3) 2-(n)-decyloxy-N,N-dimethylamphetamine; (4) 2,4-diethoxy-N,N-dimethylamphetamine; and (5) N,N-dimethyl-2,4-di-(i)-propoxyamphetamine. I believe that most of these have been iodinated and assayed in rats, and several of them appear quite promising. But none of them have been assayed in man, yet. The bromination product of 2,4-DMA (5-bromo-2,4-dimethoxyamphetamine, 5-Br-2,4-DMA) is way down in activity (see its recipe, separately). Since all iodo analogues are of about the same potency as the bromo counterparts, and since the addition of two methyl groups on the nitrogen does not appear to enhance central activity, I feel the iodination products of these N,N-dialkyl-dialkoxyamphetamines would not have any interesting psychopharmacology. There is something vaguely counterproductive, in my evaluation of things, when the goal of a research project is to avoid activity rather than to create it. Although this chemistry was completely fascinating and could have produced the world's best positron-emitting, brain-scanning diagnostic compound, I feel it quite unlikely that it would have produced the world's best insight-revealing, empathy-enhancing psychedelic, so this research direction never totally caught my fancy. I went on to other things. #54 2,5-DMA; DMA; 2,5-DIMETHOXYAMPHETAMINE SYNTHESIS: A solution of 10.0 g 2,5-dimethoxybenzaldehyde in 50 mL glacial acetic acid was treated with 6.8 g of nitroethane and 4.0 g of anhydrous ammonium acetate. This mixture was heated on the steam bath for 3 h and then the reagent/solvent was removed under vacuum. The residue was suspended in H2O and extracted with CHCl3. Removal of the solvent from the pooled extracts yielded 11.2 g of an impure 1-(2,5-dimethoxyphenyl)-2-nitropropene which, on recrystallization from 75 mL boiling MeOH, gave 6.7 g of product with a mp of 73-75 !C. Anal. (C11H13NO4) C,H,N. This nitrostyrene has been periodically available commercially from a number of sources. A solution of 17.0 g of 1-(2,5-dimethoxyphenyl)-2-nitropropene was prepared in 500 mL anhydrous Et2O. This solution was added slowly to a well-stirred suspension of 12.0 g LAH in 700 mL anhydrous Et2O. The mixture was then brought up to a reflux and maintained there for 20 h, cooled with an external ice bath, and the excess hydride destroyed by the cautious addition of H2O. Finally, a total of 500 mL H2O was added, followed by the addition of 300 g potassium sodium tartrate, and sufficient aqueous NaOH to bring the pH above 9. The two phases were separated, and the ether phase dried by the addition of anhydrous MgSO4. The drying agent was removed by filtration, and the clear filtrate saturated with a stream of anhydrous HCl gas. The formed crystals of 2,5-dimethoxyamphetamine hydrochloride (2,5-DMA) were removed by filtration, washed with anhydrous Et2O, and dried to constant weight of 16.3 g. Recrystallization from EtOH gave an analytical sample with a mp of 114-116 !C. The hydrobromide salt is reported to melt at 129-131 !C. DOSAGE: 80 - 160 mg. DURATION: 6 - 8 h. EXTENSIONS AND COMMENTARY: The qualitative information on 2,5-DMA is very sparse. I was up to a 1+ with 80 milligrams of the hydrochloride, and since it appeared to be totally a physical trip with tremors and some cardiovascular push and nothing of a sensory nature, I chose to explore it no further. A report from South America found the intoxication to be largely pleasant (this, at 75 milligrams), with an enhanced interest in one's surroundings, but no perceptual changes, no overt stimulation, and no gross physiological effects other than a slight mydriasis (dilation of the pupils). I have also been told of a single trial of 250 milligrams of the tartrate (this is equivalent to somewhere in the 150-200 milligram range of the hydrochloride salt, depending upon the acid/base ratio of the tartrate salt) with some RspeedyS effects but still no sensory changes. A seizure of capsules reported by the drug law enforcement authorities some 20 years ago found that each contained some 200 milligrams of the hydrobromide salt. This is equivalent to 170 milligrams of the hydrochloride salt, and suggests that level may be an effective dosage. An intriguing, but little studied, analogue of 2,5-DMA is the compound with methyls in place of the methoxyls. 2,5-Dimethylamphetamine has been looked at, in man, as a potential anorexic, but there is little effect even at 150 milligrams. The 3,4-isomer, 3,4-dimethylamphetamine or xylopropamine, is an adrenergic agent and it has been found to be an analgesic in man at as little as 10 milligrams. This was assayed, rather remarkably, by attaching electrodes to the tooth fillings of the experimental subjects. But with this base, cardiovascular effects were not observed until doses of about 100 milligrams were administered, and toxic effects (nausea and vomiting) were reported at 150 milligrams. There was no suggestion of anything psychedelic. All three isomers of monomethylamphetamine have also been looked at in man. The ortho- and meta-isomers, 2-methyl- (and 3-methyl- ) amphetamine are weak anorexics. At doses of up to 150 milligrams orally, there were signs of stimulation noted Q talkativeness and loss of appetite. The para-isomer, 4-methyl-amphetamine or Aptrol, is more potent. At 75 milligrams (orally, in man) there is clear adrenergic stimulation, and at twice this dosage there are signs of mild toxicity such as salivation, coughing and vomiting. There is a mystery, at least to me, concerning the commercial production of 2,5-DMA. At regular intervals, there is a public announcement of the production quotas that are requested or allowed by the Drug Enforcement Administration, for drugs that have been placed in Schedules I or II. In the Schedule I category there are usually listed amounts such as a gram of this, and a few grams of that. These are probably for analytical purposes, since there are no medical uses, by definition, for drugs in this Schedule. But there is a staggering quantity of 2,5-DMA requested, regularly. Quantities in the many tens of millions of grams, quantities that vie with medical mainstays such as codeine and morphine. I have heard that this material is used in the photographic industry, but I have no facts. Somewhere I am sure that there is someone who has to keep a lot of very careful books! In the area of psychedelic drugs, the value of 2,5-DMA is mainly in its role as a precursor to the preparation of materials that can come from a direct electrophilic attack on the activated 4-position. These uses can be found under things such as DOB and DOI and DON. The radio-halogenation of N-substituted homologues of 2,5-DMA with hypoiodite or hypofluorite is part of an extensive study underway in the search for radio-labeled brain blood flow agents. The rationale for this work is to be found in the commentary under IDNNA. In essence it has been found that the N-substitution or N,N-disubstitution of 2,5-DMA where the 4-position is unsubstituted and thus available for the introduction of a radioactive nucleus can give rise to potentially useful drugs. Most of these 2,5-dimethoxy exploratory compounds were made by the reductive alkylation of 2,5-dimethoxy-4-(radio)iodophenylacetone, using various mono or dialkyl amines. This, too, is described under IDNNA. However, the study of various direct iodinations and fluoridations that would have the N,N-dimethyl substitution on the amphetamine nitrogen atom, would require the 4-proteo- analogue, and this was made from the above nitrostyrene. A solution of the above nitrostyrene, 22.3 g 1-(2,5-dimethoxyphenyl)-2-nitropropene in 100 mL acetic acid was added to a suspension of elemental iron in acetic acid (45 g in 250 mL) and worked up with water and base washing to give, after distillation at 92-106 !C at 0.35 mm/Hg, 13.8 g 2,5-dimethoxyphenylacetone as a pale yellow oil. This underwent reductive amination with dimethylamine hydrochloride in MeOH solution, using sodium cyanoborohydride, to give the target compound 2,5-dimethoxy-N,N-dimethylamphetamine oxalate with a melting point of 133-134 !C (4.6 g ketone gave 1.38 g of salt). Anal. (C15H23NO6) C,H. It has also been prepared by the N,N-dimethylation of 2,5-DMA directly, with formaldehyde and formic acid. This has been called 2,5-DNNA, or IDNNA without the RI.S This intermediate, 2,5-DNNA, underwent direct radioiodination with labeled iodine monochloride in the presence of perchloric acid to give IDNNA with a 40% incorporation of isotope. Reaction with labeled acetyl hypofluorite, on the other hand, gave only a 2% in-corporation of the radio-isotope. This latter compound is, chemically, 4-fluoro-2,5-dimethoxy-N,N-dimethylamphetamine and, using the reasoning suggested above and with IDNNA, might best be encoded FDNNA. The 2,5-dimethylamphetamine analogue mentioned above was also explored in this IDNNA concept. The commercially available 2,5-dimethylbenzaldehyde was converted to the nitrostyrene with nitroethane (1-(2,5-dimethylphenyl)-2-nitropropene, yellow crystals with a melting point of 24.5-25.5 !C) which reacted with elemental iron in acetic acid to give the ketone 2,5-dimethylphenylacetone (boiling at 140-150 !C at 0.4 mm/Hg). Reductive amination with dimethylamine and sodium cyanoborohydride gave 2,5-DMNNA (2,5,N,N-tetramethylamphetamine) as a clear oil with a boiling point of 115-125 !C at 0.35 mm/Hg. It gave poor yields of the 4-fluoro analogue with acetyl hypofluorite. All of these latter materials remain unevaluated in man. #55 3,4-DMA; 3,4-DIMETHOXYAMPHETAMINE SYNTHESIS: A solution of 33.2 g of veratraldehyde in 15.0 g nitroethane was treated with 0.9 g of n-amylamine and placed in a dark place at room temperature. In a day or so, separated H2O was apparent and, after a couple of weeks, the mixture completely solidified. The addition of 50 mL EtOH and heating effected complete solution and, on cooling, this provided 1-(3,4-dimethoxyphenyl)-2-nitropropene as yellow crystals, 29.0 g, with mp of 70-71 !C. The more conventional reaction scheme, 6 h heating of a solution of the aldehyde and nitroethane in acetic acid with ammonium acetate as catalyst, gave a much inferior yield of product (33.2 g gave 14.8 g) of the same purity. Recrystallization from MeOH increased the mp to 72-73 !C. To a refluxing suspension of 7 g LAH in 600 mL anhydrous Et2O, stirred and under an inert atmosphere, there was added 7.5 g 1-(3,4-dimethoxyphenyl)-2-nitropropene by allowing the returning condensed ether to leach out the material as a warm solution from a Soxhlet thimble. Following the completion of the addition of the nitrostyrene, refluxing was maintained for 24 h, and the reaction mixture allowed to stand several days at room temperature. The excess hydride was destroyed by the cautious addition of 500 mL H2O containing 40 g H2SO4, and the phases were separated. The aqueous phase was washed with both Et2O and CH2Cl2. There was then added 200 g potassium sodium tartrate, and the pH brought above 9 by the addition of aqueous NaOH. This clear solution was extracted with 3x150 mL CH2Cl2, the extracts were pooled, and the solvent removed under vacuum to give a residual oil. This was dissolved in Et2O, saturated with anhydrous HCl gas, and the resulting solids removed by filtration. Recrystallization from 10 mL acetone gave 1.35 g 3,4-dimethoxyamphetamine hydrochloride (3,4-DMA) as beautiful white crystals with a mp of 144-145 !C. DOSAGE: a few hundred milligrams. DURATION: unknown. QUALITATIVE COMMENTS: (with 70 mg i.v.) [One patient received 0.004 mM/Kg of the hydrochloride salt intravenously and exhibited only slight increase in psychiatric symptoms; a comparable dosage in a second individual also elicited only insignificant changes.] (with 700 mg i.v.) [When one of these patients was reinjected at a later date with approximately 0.04 mM/Kg of 3,4-DMA a definite Tmescaline-likeU state was induced. The symptoms included colored hallucinations of geometric figures and occasional structured forms. The other individual experienced visual distortions, notable after-imagery, feelings of unreality, and paranoid ideas. Marked mydriasis and gross body tremors also occurred but apparently no hallucinations were experienced.] EXTENSIONS AND COMMENTARY: These RQualitative CommentsS are not explicit quotations from people who had taken 3,4-DMA. They are written descriptions by the observers who had given 3,4-DMA to psychiatric patients. This is one of the most outrageous chapters in the books on military medicine. The chemical warfare group within the U.S. Army explored many potential psychedelics by administering them to innocent patients with not even a thought of obtaining informed consent. These experiments took place at the New York State Psychiatric Institute (amongst other places) in the early 1960Us. The Edgewood Arsenal code name for 3,4-DMA was EA-1316. A few non-military studies have indicated that 3,4-DMA is orally active at 160 milligrams, and so probably its potency by this more conventional route would fall midway between that of mescaline and of MDA. The 3-methoxy-4-other-than-methoxy things (such as hydroxy, ethoxy, allyloxy and methyl) are mentioned in the recipe for MEPEA. The alpha-ethyl homologue of 3,4-DMA, 2-amino-1-(3,4-dimethoxyphenyl)butane, and of other DMA's are discussed under the recipe for ARIADNE. There are a total of six possible amphetamine molecules with two methoxyl groups attached. The 3,4-orientation has always been the most appealing to the life scientists as this is the positional substitution pattern found in the natural neuro-chemicals dopamine, norepinephrine and epinephrine. These latter two are called noradrenalin and adrenalin in England. Two adjacent hydroxy groups represent the catechol in the well known word catecholamines. You might read in a textbook, RThis is where nature placed the groups when she put the compounds in our brains. So that is where the groups might be the most interesting in a psychedelic.S Why? I have never understood this kind of reasoning. If a possible psychedelic has just the exact oxygen positioning of a neurotransmitter, then, voila, that's why it is active. And if a possible psychedelic has some positioning of these oxygen atoms that is different than that of a neurotransmitter? Then voila again. That's why it is active. Both sound equally reasonable to me, and neither one even begins to address the fundamental question, how do the psychedelic drugs do what they do? A study in the human animal of the intimate effects of one of these neurotransmitter analogues might bring us a little bit closer to answering this fundamental question. But maybe it wouldnUt, after all. Nothing has made much sense so far! Anyway, 3,4-DMA is one of the ten essential amphetamines that can, in theory, arise from the ten essential oils of the spice and herb trade. In this case, the origins are methyl eugenol and methyl isoeugenol. Two of these RdifferentS isomers, 2,4-DMA and 2,5-DMA, have already been discussed in their own separate recipes. And the remaining three of the six possible DMA's that are RdifferentS have been made and studied pharmacologically in animals but not in man. These are the 2,3-DMA, 2,6-DMA and the 3,5-DMA isomers. The products of their reaction with elemental bromine are discussed under META-DOB. Both the 2,6- and the 3,5-isomers, as the N,N-dimethyl homologues, have been looked at as potential radio-halogen recipients in the search for positron-emitting brain blood-flow indicators, as discussed in the recipe for IDNNA. Both were made from the appropriate nitrostyrene via the corresponding phenylacetone. The 2,6-isomer was derived from 2,6-dimethoxybenzaldehyde. This, in nitroethane and ammonium acetate, gave the nitrostyrene as canary-yellow crystals from MeOH that melted at 101.5-102.5 !C. Elemental iron in acetic acid converted this nitrostyrene to 2,6-dimethoxyphenylacetone (a water-white oil with boiling point of 95-105 !C at 0.4 mm/Hg. Anal. (C11H14O3) C,H) and reductive amination with dimethylamine and sodium cyanoborohydride gave 2,6-dimethoxy-N,N-di-methylamphetamine perchlorate (2,6-DNNA) with a melting point of 109-110 !C. This base was readily fluorinated with 18F acetylhypofluorite and iodinated with chloramine-T-oxidized 122I iodide ion. It was also halogenated with (non-radioactive) bromine and iodine monochloride to give the corresponding 3-bromo-(and 3-iodo)-2,6-dimethoxy-N,N-dimethylamphetamines but these, in turn, did not react with radioactive acetyl hypofluorite. The 3,5-isomer followed precisely the same flow sheet. 3,5-Dimethoxybenzaldehyde gave the nitrostyrene (with a melting point of 87-88 !C), the phenylacetone (with a boiling point of 110-130 !C at 0.3 mm/Hg) and the product 3,5-dimethoxy-N,N-dimethylamphetamine perchlorate (3,5-DNNA) with a melting point of 100-101 !C. This also reacted readily with 18F acetylhypofluorite and 122I-hypoiodite. Several alpha-ethyl homologues of these compounds have also been discussed in the recipe for ARIADNE. #56 DMCPA; 2-(2,5-DIMETHOXY-4-METHYLPHENYL)CYCLOPROPYLAMINE SYNTHESIS: To a solution of 25 g 2,5-dimethoxy-4-methylbenzaldehyde (see the recipe for 2C-D for the preparation) and 29.2 g malonic acid in 50 mL anhydrous pyridine, there was added 2 mL piperidine and this was heated on the steam bath for several h. The mixture was added to a solution of 125 mL concentrated HCl in 500 mL H2O at 0 !C, and the solid product that was formed was removed by filtration, and washed with H2O. Recrystallization from aqueous EtOH yielded 31 g 2,5-dimethoxy-4-methylcinnamic acid with a mp of 163-166 !C. Anal. (C12H14O4) C,H. In a cooled high-pressure reaction vessel there was placed a suspension of 30 g 2,5-dimethoxy-4-methylcinnamic acid in 150 mL liquid isobutene. This was treated dropwise with 0.6 mL concentrated H2SO4, then sealed and brought to room temperature. After 48 h shaking, the vessel was cooled again to -10 !C, opened, and poured into 200 mL of 10% Na2CO3. This was extracted with hexane, the pooled extracts washed with H2O, and the solvent removed to yield 17.0 g of (t)-butyl 2,5-dimethoxy-4-methylcinnamate as an amber oil. Anal. (C16H22O4) C,H. The cyclopropane ester was prepared by the reaction between 16 g (t)-butyl 2,5-dimethoxy-4-methylcinnamate and dimethylsulfoxonium methylide, prepared as described in the Kaiser reference in the acknowledgements. Hydrolysis of this ester gave 53% trans-2-(2,5-dimethoxy-4-methylphenyl)cyclopropanecarboxylic acid which, after recrystallization from a MeOH/H2O mixture, had a mp of 136 !C. Anal. (C13H16O4) C,H. A suspension of 4 g of trans-2-(2,5-dimethoxy-4-methylphenyl)cyclopropanecarboxylic acid in an equal volume of H2O, was treated with sufficient acetone to effect complete solution. This was cooled to 0 !C and there was added, first, 2.0 g triethylamine in 35 mL acetone, followed by the slow addition of 2.5 g ethyl chloroformate in 10 mL acetone. This was stirred for 0.5 h, and then there was added a solution of 1.7 g NaN3 in 6 mL H2O, dropwise. After 1 h stirring at 0 !C, the mixture was quenched by pouring into H2O at 0 !C. The separated oil was extracted with Et2O, and extracts dried with anhydrous MgSO4. Removal of the solvent under vacuum gave a residue of the azide, which was dissolved in 10 mL anhydrous toluene. This solution was heated on the steam bath until the nitrogen evolution was complete, and the removal of the solvent under vacuum gave a residue of crude isocyanate as an amber oil. This intermediate isocyanate was dissolved in 5.4 g benzyl alcohol and the reaction mixture was heated on the steam bath for 6 h. The excess benzyl alcohol was removed by distillation, yielding trans-2-(2,5-dimethoxy-4-methylphenyl)carbobenzoxyamidocyclopropane as a crystalline residue. This was recrystallized from an EtOAc/hexane mixture to give 6.13 g of a crystalline product with a mp of 107-108 !C. Anal. (C20H23NO4) C,H,N. A solution of 1.5 g trans-2-(2,5-dimethoxy-4-methylphenyl)carbobenzoxyamidocyclopropane in 120 mL MeOH containing 200 mg 10% Pd/C was shaken under hydrogen gas at 35 psig for 45 min. The solution was filtered through celite, and a sufficient amount of a solution of 5% HCl in EtOH was added to the filtrate to make it acidic. Removal of all volatiles under vacuum gave a solid residue that was recrystallized from an EtOH/ether mixture to give 0.98 g of trans-2-(2,5-dimethoxy-4-methylphenyl)cyclopropylamine hydrochloride (DMCPA) as white crystals with a mp of 210-211 !C. DOSAGE: 15 - 20 mg. DURATION: 4 - 8 h. QUALITATIVE COMMENTS: (with 10 mg) The effects were quite real at an hour, but very hard to define. Nothing left at four hours, but my sleep was filled with bizarre and colorful dreams. Something was still working somewhere, at some level. (with 20 mg) I found myself lightheaded, and the thinness seemed to be, rather remarkably, on the left side of my brain. The experience was flighty. I was reminded of the aura that has been described preceding a convulsion. I was decoupled from my experience and from my environment. Not all of the control is there, and I am uncomfortable. But in an hour, there is complete control again, and I can relax my conscious guard which allows an easy plus three. With this, there was easy fantasy, erotic, quite a bit of movement in the visual field, and mild anorexia. The residual hyperreflexive thinness is largely gone, and not at all worrisome. This stuff is complicated, with a little too much of the physical. The next day was without any residues at all. EXTENSIONS AND COMMENTARY: Most of the human trials took place in the fifteen to twenty milligram range. Several reports describe some muscular tremor, especially in the earliest part of the experience, but this never seemed to be a concern. The efforts to lock imagery to music were not too successful. All of these clinical studies were conducted on the trans-compound, but on the racemic mixture. This has been resolved into the two optical isomers, but they have not been compared in man. The cis-mixture is unknown. This material is intimately related to tranylcypromine, a clinically proven antidepressant. This drug is a known monoamine oxidase inhibitor, and it is certainly possible that some of this pharmacological property might be found in DMCPA if it were to be looked for. The hints of physical toxicity at the higher doses assayed might suggest some such activity. This compound, DMCPA, was modeled directly after the structure of DOM, with the 2,5-dimethoxy-4-methyl substitution pattern. Another analogue of tranylcypromine, similarly modeled, is 3,4,5-trimethoxytranylcypromine, or trans-2-(3,4,5-trimethoxyphenyl)cyclopropylamine (TMT). It has been evaluated at levels of only 13 milligrams orally, and at this dose there were no hints of central activity. #57 DME; 3,4-DIMETHOXY-'-HYDROXYPHENETHYLAMINE SYNTHESIS: To a solution of 10.2 g 3,4-dimethoxybenzaldehyde in 10 mL EtOH, cooled to 0 !C, there was added a solution of 4.2 g KCN in 40 mL H2O. With good stirring, there was slowly added 10 mL concentrated HCl (caution: HCN is evolved) and the two-phase reaction mixture was allowed to continue stirring until there was the spontaneous formation of crystals. After a few days standing, these were removed by filtration and well washed with H2O. All was recrystallized from 75 mL of 50% MeOH and air dried to provide 6.95 g of the cyanohydrin 3,4-dimethoxy-a-hydroxyphenylacetonitrile. The mp was 104-106 !C, which can be increased to 109 !C by recrystallization from benzene. A well-stirred suspension of 4.7 g LAH in 500 mL anhydrous Et2O was brought up to a gentle reflux, and 4.7 g 3,4-dimethoxy-a-hydroxyphenylacetonitrile was leached in from a Soxhlet thimble, over the course of 3 h. The color of the ether solution progressed from yellow to green, to an eventual blue. The reflux was maintained for 16 h. After cooling again, there was added (carefully) a solution of 27 g H2SO4 in 500 mL H2O. The completely clear two-phase mixture was separated, and the aqueous phase treated with 87 g potassium sodium tartrate. The addition of 25% NaOH brought the pH >9, and this phase was extracted with 4x100 mL CH2Cl2. Removal of all the organic solvents under vacuum gave a residue that was part oil and part solid. This was extracted with 4x50 mL boiling Et2O, the extracts pooled, and saturated with anhydrous HCl gas. The 0.95 g of pale-yellow crystals that formed were removed by filtration, and finely ground under 5 mL CH3CN. There remained, after refiltration and air drying, 0.85 g of 3,4-dimethoxy-'-hydroxyphenethylamine hydrochloride, DME, with a mp of 170-172 !C. DOSAGE: greater than 115 mg. DURATION: unknown. QUALITATIVE COMMENTS: (with 115 mg) I was faintly nauseous about an hour after taking the compound, and perhaps I was more alert than usual in the evening. Substantially no effects. EXTENSIONS AND COMMENTARY: The rationale for exploring the beta-hydroxylated phenethylamines, especially those with oxygens at the biologically important 3- and 4-positions, has already been presented. Norepinephrine is a '-hydroxylated phenethylamine with oxygens at these two ring positions. With DME, these are masked as two methyl ethers, and the initials DME stand for 3,4-dimethoxyphenyl-'-ethanolamine. This is an alternate name for 3,4-dimethoxy-'-hydroxyphenethylamine. An exactly analogous compound is 3,4-methylenedioxy-'-ethanolamine, where the masking is done with the biologically more fragile methylenedioxy ether. Originally I had called this compound MDE (methylenedioxyethanolamine) but that code has been, since 1975, used exclusively for 3,4-methylenedioxy-N-ethylamphetamine, which is a recipe all by itself. Under the discussion of members of the BOX series, there is a methylenedioxyphenethylamine with a methoxyl group at the '-position, and it is called BOH (q.v.). There, a reasonable code name for this specific compound is given, namely BOHH. RBOS stands for the beta-oxygen function on a phenethylamine; this is the heart of the BOX family. The RHS which is the third letter of BOHH stands for the free hydroxyl group. And the final RHS is for homopiperonylamine (which is the trivial name for the compound without the hydroxyl group). BOHH, or 3,4-methylenedioxy-'-hydroxyphenethylamine, or 3,4-methylenedioxy-'-ethanolamine, has also be assayed in man at up to 100 milligrams without any effects, and must be considered, as of now, to be inactive centrally. The possible toxic roles of '-ethanolamines as potential adrenolytic agents, have been discussed in the BOHD recipe. And beware of the use of the code name MDE in the very old literature. It might be this BOHH compound. #58 DMMDA; 2,5-DIMETHOXY-3,4-METHYLENEDIOXYAMPHETAMINE SYNTHESIS: Apiole, as the crystalline essential oil 1-allyl-2,5-dimethoxy-3,4-methylenedioxybenzene, is isolated directly from commercial Oil of Parsley, by careful fractional distillation. It is the fraction that boils at 165-167 !C at 27 mm/Hg. A solution of 19.8 g apiole in a mixture of 43 g KOH and 60 mL hot EtOH was heated in the steam bath for 24 h. With vigorous stirring, it was diluted with H2O, at a rate which the crystals that formed spontaneously could accumulate from the turbidity that was generated. When no more H2O could be added (there was persistent oiling out of material) the reaction mixture was filtered to give 12.1 g of an amber solid material. This was recrystallized from 20 mL boiling hexane, which was filtered while hot to remove insolubles. From the cooled filtrate, there was obtained 9.3 g of 2,5-dimethoxy-3,4-methylenedioxy-1-propenylbenzene, isoapiole, as pale cream-colored solids. A stirred solution of 8.8 g 2,5-dimethoxy-3,4-methylenedioxy-1-propenylbenzene and 3.9 g pyridine in 45 mL acetone was cooled to ice-bath temperatures, and treated with 7.9 g tetranitromethane. This extremely dark reac-tion was stirred at 0 !C for 5 min, then quenched with a solution of 2.6 g KOH in 45 mL H2O. With continued stirring, there appeared yellow crystals of 1-(2,5-dimethoxy-3,4-methylenedioxyphenyl)-2-nitropropene which, after filtering, washing with 50% acetone and air drying, weighed 8.0 g and had a mp of 110-111 !C. To a well-stirred and gently refluxing suspension of 6.3 g LAH in 500 mL anhydrous Et2O, under an inert atmosphere, there was added 7.5 g 1-(2,5-dimethoxy-3,4-methylenedioxyphenyl)-2-nitropropene by leaching out the nitrostyrene from a thimble in a modified Soxhlet condenser apparatus. The addition took 1.5 h, and the refluxing was maintained for an additional 3 h. After cooling, the excess hydride was destroyed by the cautious addition of 300 mL of 1.5 N H2SO4. The aqueous phase was brought to a pH of 6 with Na2CO3. This was heated to 80 !C and clarified by filtration though paper. The addition of a stochiometric amount of picric acid in boiling EtOH gave rise to precipitation of the product picrate as globs that did not crystallize. These were washed with cold H2O, then dissolved in 30 mL 5% NaOH. Extraction with 2x75 mL Et2O, and the stripping of the solvent from the pooled extracts, gave 3.1 g of an oily residue which, upon dissolving in 250 mL Et2O and saturation with anhydrous HCl gas, gave white crystals. These were removed by filtration, Et2O-washed, and air dried, to give 2.9 g of 2,5-dimethoxy-3,4-methylenedioxyamphetamine hydrochloride (DMMDA) that melted in the 165-175 !C range. DOSAGE: 30 - 75 mg. DURATION: 6 - 8 h. QUALITATIVE COMMENTS: (with 25 mg) The intoxication was there at an hour and a quarter, and I was hit with nausea with no particular warning. I am shaky, a little dilated in the eyes, and there is a modest depersonalization (reminding me of LSD). Time might be slightly slowed, and there is a mild ataxia in the legs. A couple of hours later, all effects are going away fast. I ate an apple, but maybe my mouth didnUt work quite right. The apple was incredibly noisy. (with 32 mg) I am up to a 2 1/2 plus at something after two hours, with no apparent visuals, no push, no erotic. And a few hours later it is quietly slipping away. It felt completely safe, and without any conspicuous psychedelic action, at least at this level. (with 50 mg) I took graded doses of 10 milligrams every thirty minutes for a total of 50 milligrams, and there were no effects at all. (with 50 mg) In the middle of this all, I found myself getting into abstract thinking, and maybe some imagery as well. The effects were disappointingly light. (with 75 mg) This was equal to somewhere between 75 and 100 micrograms of LSD. I was caught up with the imagery, and there was an overriding religious aspect to the day. The experience had an esthetic value. I liked it. EXTENSIONS AND COMMENTARY: DMMDA was the first of the tetraoxygenated amphetamine derivatives that was ever explored in man, back in 1962. And it is not easy to find an acceptable single phrase to describe its action or an acceptable number to describe its potency. I have put the value of 10 mescaline units (M.U.) into the literature and this would imply that maybe 30 milligrams was an active dose. This is probably too low, and some day I would like to run an experiment with the entire research group with this compound to see just what it really does. The essential oil that corresponds to DMMDA is, of course, apiole from the Oil of Parsley, which again ties together the spice world and the amphetamine world. And there is isoapiole, also a natural thing. This pair represents the ring-substitution pattern of one of the ten essential oils and DMMDA is one of the ten essential amphetamines. Several people have asked me what I thought about the potential activity of a compound with a methyl group added to DMMDA. One of these possibilities would be the N-methylated derivative, 2,5-dimethoxy-N-methyl-3,4-methylenedioxyamphetamine, or METHYL-DMMDA (or DMMDMA for the dimethoxy-methylenedioxy-methamphetamine nomenclature). It is a MDMA analogue, and is described in the recipe for METHYL-MMDA-2. The placement of an added methyl group onto the '-position of DMMDA, rather than on the nitrogen atom, produces a pair of stereoisomeric homologues. These are the threo- (or-trans-) and erythro- (or cis)-2,5-dimethoxy-'-methyl-3,4-methylenedioxyamphetamines. They have never been assigned trivial names (my original codes for them were S-1495 and S-1496 which is not too intuitively informative). Their chemically proper names would have the 2-amino-3-substituted phenylbutane form. The synthesis of these DMMDA homologues started with the reduction of the nitrosyrene to the ketone (see under METHYL-MMDA-2 for this preparation), followed by methylation with fresh sodium isopropoxide and methyl iodide, to give the beta-methyl product. This formed the two possible oximes, one with a mp of 120 !C, and the other from MeOH with a mp of 146 !C. The 120 !C oxime, with fresh sodium ethoxide gave threo-2-amino-3-(2,5-dimethoxy-3,4-methylenedioxyphenyl)butane hydrochloride. This salt had a mp of 247-249 !C. The 146 !C oxime gave erythro-2-amino-3-(2,5-dimethoxy-3,4-methylenedioxyphenyl)butane hydrochloride with a mp of 188-189 !C. The threo-isomer showed a possible threshold effect at 80 milligrams, with hyperventilation and perhaps some mental muddiness. The erythro-isomer showed no effects, but it had been taken up only to 10 milligrams. The only other '-methyl homologue of an active material that was explored chemically, was related to MDA. The ketone (3,4-piperonylacetone, see under MDMA) was methylated with sodium isopropoxide and methyl iodide, and a crystalline oxime was obtained. Reduction with Zn dust gave what appeared to be 2-amino-3-(3,4-methylenedioxyphenyl)butane hydrochloride, but there were sufficient uncertainties (possible dimethylation, only one oxime isolated, the need of strong reducing conditions) that the entire project was placed in, and still is in, an indefinite holding pattern. The similar analogues for DOM are the two Classic Ladies, DAPHNE and ELVIRA, and they, too, are for some time in the future. #59 DMMDA-2; 2,3-DIMETHOXY-4,5-METHYLENEDIOXYAMPHETAMINE DOSAGE: about 50 mg. DURATION: unknown. QUALITATIVE COMMENTS: (with 50 mg) I am into it; it is much like MDA. EXTENSIONS AND COMMENTARY: This is pretty sparse information upon which to build a picture of biological activity. First, the synthesis was done by someone else and, as I have not been able to find where the notes are, this will be the one recipe in the footnote without explicit directions incorporated. The procedure used was exactly the same as that described for DMMDA, except that the starting material was dillapiole rather than apiole. The dillapiole was obtained by the careful fractionation of Oil of Dill (as opposed to the isolation of apiole from the careful fractionation of Oil of Parsley). Isomerization to isodillapiole, nitration with tetra-nitromethane to give 1-(2,3-dimethoxy-4,5-methylenedioxyphenyl)-2-nitropropene, and its reduction with LAH in ether to give 2,3-dimethoxy-4,5-methylenedioxyamphetamine hydrochloride (DMMDA-2) proceeded in a precisely analogous manner to the preparation of DMMDA. And the pharmacological part is rather thin as well. I was not the taster, and can only quote what I had been given. This same observer found a threshold at 28 milligrams. Under other circumstances, this comment on DMMDA-2 would have been tucked into the commentary on DMMDA where it belongs, but the activity level was called for in a large review article, and on the basis of the above, both its initials and the value of 5x the potency of mescaline were permanently enshrined in the published literature. What is it really like? I donUt know. Its structure is an appealing amalgamation of that of MMDA and MMDA-2, and it might be quite a winner if the dosage and the duration were known. It is, after all, one of the ten essential amphetamines, since dillapiole is one of the ten essential oils. At the time that DMMDA and DMMDA-2 were synthesized, I had visions of doing the same thorough study with these as I had set up with the TMA's (six possible, six done) and the MMDAUs (six possible, five done). Here, too, with a pair of methoxy groups on an amphetamine skeleton, with a methylenedioxy ring thrown in, six isomers are possible but only these two have been prepared. The unknown ones will certainly be called DMMDA-3, -4, -5 and -6, but the assignments of code to structure havenUt even been thought out yet. The remarkable and totally unexpected activity of DOM was discovered at about this time and it was a much more tempting direction to follow. The remaining four possible DMMDA's have been left to that famous time, a future Rrainy day. .
