Here's another for you guys;
Tet. Lett. 3, 261 1973 B.L. Sondengram e.a.
Formaline(35%,35mmol) was added with strong stirring to a solution of tryptamine(primary amine) 3 mmol in methanol(10 ml) and the solution was refluxed for 30 min. After cooling
400mg NaBH4 was added slowly. After 1 hour the reaction was evaporated and the mixture was extracted with CHCL2. Evaporation yields
Dimethyl-tryptamine,85%
Also have another that uses ZnCl2,paraformaldehyde,Primary or secondary amine,in CH2CL2. NaBH4 reduced also. SWIM has been contemplating the Tet. synth, seems to be a relatively simple way to get there.
