Reaction Steps

To a mixture of tryptamine 1.0 g (6.2 mmol) in a mixture of CHCl3 and H2O, was added 1.1 g (6.2 mmol) benzylchloroformate, followed by dropwise addition of sat. NaHCO3 solution to maintain alkaline conditions. The reaction was stirred for 2 hrs. The reaction was extracted with CHCl3 and the organic layer was concentrated to dryness giving a dark yellow oil. The oil was crystallized from ethanol/water to give an off-white crystalline product.
