 | | The extracts were pooled, and the solvent removed under vacuum to provide a residue of 0.12 g N,N-dimethyltryptamine (DMT) as a crystalline solid, with a mp of 57-59 °C. IR (in cm-1): 732, 740, 811, 859, 1011, 1037, 1110, 1171. |
 | | This was pressed on a porous plate and washed with petroleum ether to give N,N-dimethyltryptamine (DMT) as an off-white solid with a mp of 47 °C. The demethylation of the thiophenolate salt: A suspension of 2.5 g N,N,N-trimethyltryptammonium iodide in 25 mL MeOH was brought into solution by heating, and treated with 1.0 g Ag2O. |
 | | There was thus obtained 0.40 g of dimethyltryptamine (DMT) with a mp 67-68 °C. The distillate contained about 3% of 2-Methyl-1,2,3,4-tetrahydro-b-carboline (parent peak mass 186, major peak mass 186) as an impurity which was lost upon recrystallization. |
