Tryptamine → HCID 930813, compound

Participants

Reaction Steps

Tryptamine (1.04 g, 6.5 mmol) was dissolved in a mixture of acetone (20 ml) and triethylamine (1 ml) under a nitrogen atmosphere. Benzyl isocyanate (952 mg, 7.15 mmol, 0.88 ml) was swiftly added dropwise at 0° C. and the mixture was then subsequently stirred for 2 h, while cooling with ice, and at RT for 2 h. A subsequent TLC in chloroform/methanol 20:1 showed only small amounts still of tryptamine. The mixture was concentrated i. vac. The residue obtained was purified by flash chromatography with 100 g of silica gel and chloroform/methanol 20:1→9:1→4:1.
