Ok, if you started out w/ tryptamine in a resonably pure form, would an STP Urushibara Catalyst reaction be an adequate reducing environment to run something like a TIHKAL #47 'cept w/ twice the acetone?
TIHKAL #47:
"The crude N-methyltryptamine obtained above (which can be substituted with 1.20 g of pure NMT) was dissolved in 50 mL ethanol, treated with 1.0 mL acetone, then with 0.5 g 10% Pd/C, and the reaction mixture shaken under a hydrogen atmosphere at 50 psi for 15 h. The catalyst was removed by filtration through a bed of Celite, the filtrate was stripped of solvent under vacuum, and the solid residue recrystallized from Et2O/hexane to give 0.93 g N-methyl-N-isopropyltryptamine (MIPT) which had a mp 82-83 °C. Fom the benzyloxycarbonyltryptamine, yield was 56%. From NMT the yield was 62% of theory. Anal: C14H20N2. C,H,N. MS (in m/z): C5H12N+ 86 (100%); indolemethylene+ 130 (10%); parent ion 216 (2%). Efforts to isopropylate NMT with an excess of isopropyl iodide in isopropanol gave a 51% yield of a distilled product that did not crystallize."
