SYNTHESIS: A solution of 6.96 g 2,5-dimethoxyamphetamine hydrochloride (2,5-DMA) in 250 mL H2O was made basic with aqueous NaOH and extracted with 3×75 mL CH2Cl2. After removal of the solvent from the pooled extracts under vacuum, the residual free base was dissolved in 36 g glacial acetic acid and, with good stirring, cooled to 0 °C with an external ice bath. There was then added, with a Pasteur pipette, 3 mL of liquid chlorine. The generation of HCl was evident, and the reaction was allowed to stir for an additional 3 h. The mixture was then poured into 300 mL H2O and washed with 3×100 mL Et2O. The aqueous phase was made basic with NaOH and extracted with 3×150 mL CH2Cl2. After removal of the solvent from the pooled extracts, the residue was dissolved in Et2O and saturated with anhydrous HCl gas. There was the formation of a heavy oily precipitate. The ether supernatent was decanted, and the residue was intimately mixed with 200 mL of fresh anhydrous Et2O. Everything set up as an off-white crystalline mass weighing 2.3 g. This was dissolved in 12 mL of boiling MeOH and diluted with 230 mL boiling Et2O. The clear solution was quickly filtered to give a clear, pale amber mother liquor, which soon started depositing lustrous white crystals. After filtering, Et2O washing, and air drying to constant weight, there was obtained 1.4 g of 2,5-dimethoxy-4-chloroamphetamine hydrochloride (DOC) From the mother liquors (from the original HCl saturation) an equal amount of product could be obtained by exploiting the acetone insolubility of the hydrochloride salt of the product. The published mp of this salt, from acetone/EtOH, is 187-188 °C. A sample of this hydrochloride salt, prepared from the amino analogue via diazotization and eventual hydrolysis of an acetylated precursor, was recrystallized from EtOH/ether and had a mp of 193-194.5 °C.
DOSAGE: 1.5 – 3.0 mg.

DURATION: 12 – 24 h.

QUALITATIVE COMMENTS: (with 1.6 mg) I was hit with a slightly light head; the effects were quite real. I was disconnected, and somehow spacey, but this was a favorable spacey which was kind of fun. Somewhere at about the sixth hour I realized that I was beginning to drop off a bit, but six hours later yet, there was still a lot of memory. This is a long thing.

(with 2.4 mg) This is what I might call an archetypical psychedelic. Everything is there in spades, with few if any of the subtle graces, the `gentle images‘ and `gentle fantasies‘ of the 2-carbon phenethylamines. This is the works. There are visuals, and there are interpretive problems with knowing just where you really are. The place where nothing makes sense, and yet everything makes sense. I have just slept for a few hours, and now I am awake and it has been eighteen hours, and there is a lot still going on, although I have a relaxed, good feeling. Anyone who uses this had better have 24 hours at their disposal.

(with 2.4 mg) Here I am at the sixth hour, and I am still roaring along at a full plus three. I have established that this material is neither anti-erotic nor anorexic. The body is very comfortable, and so is the mind. There is an interesting aspect, perhaps peculiar only to this experiment and under these conditions. With my eyes closed the fantasy is a completely dark screen, lovely and seductive, subtle, and yet light must be deliberately brought in. This is not in any way negative for being in the dark, but is just unusual. I will have to try this in the daylight next time, to see what the eyes-closed brings to the mind-screen. At 24 hours, I have found that my sleep was not too great. My dreams were tight, and I kept defending against trouble; the nervous system was too alert. I was in a good humor, though, and I still am. This is excellent stuff, but start early in the day.

EXTENSIONS AND COMMENTARY: It is clear that the three halo-amphetamine derivatives, DOI, DOB and DOC, are all pretty much of the same potency. And all of them very long lived. The difference between the various halogen atoms was brought up under the 2C-C discussion. DOC is clearly a long-lasting, dyed-in-the-wool psychedelic.

In the making of this, by the procedures that have been followed in Canada, there are two chemical intermediates which might, some day, be looked at as potential psychedelics under their own colors. Reduction of the compound that is called DON in this Book II (2,5-dimethoxy-4-nitroamphetamine hydrochloride) with Pd/charcoal and hydrogen, gives the 4-amino derivative. This is 2,5-dimethoxy-4-aminoamphetamine dihydrochloride, DOA, which melts at 248-250 °C. And the reduction of an oxime intermediate gives rise to the acetamido analogue, 2,5-dimethoxy-4-acetamidoamphetamine hydrochloride, DOAA, with a mp of 249-250 °C. Neither compound has been tasted, but someday this omission will be corrected. DOA and DOAA have a sinister ring to them, however, and some changes of terminology might be needed. DOA, in the coroner’s vocabulary, means Dead-On-Arrival. But then, AMA (the American Medical Association) just happens to also mean (in the jargon of emergency medicine) Against-Medical-Advice. Everything averages out, somehow. Remember that the amyl homolog (amyl at the 4-position) follows the 4-letter convention of all of the DOM homo-logues, and has the code name of DOAM. Thus, DOA, amino; DOAA, acetamido, and DOAM, amyl.

One must learn to keep one’s sense of humor. The immortal humorist Wavy Gravy once said, „If you can’t laugh at life, it just isn’t funny anymore.“ The code name of this compound, 2,5-dimethoxy-4-chloroamphetamine is, after, all, DOC. This should certainly appeal to some physicians.
