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. Cyclopentyl isocyanate (795 mg, 7.15 mmol, 0.81 ml) was swiftly added dropwise at 0° C. and the mixture was then subsequently stirred for 2H, while cooling with ice, and at RT overnight. A white solid had precipitated out of the solution, and was filtered off with suction and rinsed with acetone. It was 641 mg of pure product. The filtrate was concentrated i. vac. and the residue was then stirred thoroughly with acetone (10 ml). The undissolved white solid was filtered off with suction and rinsed with acetone, and a further 612 mg of pure product were obtained in this way.
