Acetic Acid → HCID 10221947, compound

Participants

Reaction Steps

348 mg DL-α-methyltryptamine were dissolved in dry 1,2-dichloroethane (10 ml) under argon (clear solution), 463 mg 4-benzyl-4-dimethylamino-cyclohexane (see example 3) and glacial acetic acid (229 μl) were added and the mixture was stirred for one hour at RT. 550 mg sodium triacetoxyborohydride were then added and the suspension was stirred for a further 72 hours at RT. For working up, water (20 ml) was added to the reaction mixture, the organic phase was separated off and the aqueous phase was extracted once with ether and then rendered strongly alkaline with sodium hydroxide solution (pH>10). A gelatinous precipitate which dissolved in ethyl acetate thereby precipitated out. The aqueous phase was extracted with ethyl acetate (4×10 ml). All the ethyl acetate phases were combined, dried with sodium sulfate and concentrated to dryness. 766 mg of a mixture of cis- and trans-1-benzyl-N′-[2-(1H-indol-3-yl)-1-methylethyl]-N,N-dimethylcyclohexane-1,4-diamine were obtained as a vitreous solid (m.p. 48-53° C.).
