Triethylamine → N-[(Benzyloxy)carbonyl]glycylglycinamide

Participants

Reaction Steps

N-benzyloxycarbonylglycine (3 g, 14.4 mmole) were dissolved in 200 mL of dichloromethane and 4.5 g (21.6 mmole) of DCC were added. The mixture was stirred at room temperature for 2 hours, the insoluble materials were removed and 3.2 g (28.8 mmole) of glycinamide hydrochloride and 2.93 g (28.8 mmole) of TEA (triethylamine) were added to the filtrate. The reaction was stirred for 24 hours at room temperature, the insoluble materials were filtered and the filtrate was evaporated to dryness in vacuum. The residue was recrystallized from distilled water to get a pure product 1.9 g (7.2 mmole), yield of 50%.
