Ammonia → ((S)-4-Amino-4-carbamoyl-butyl)-carbamic acid benzyl ester

Participants

Reaction Steps

(S)-2-Amino-5-benzyloxycarbonylamino-pentanoic acid methyl ester (2.80 g, 9.99 mmol) and 7M NH3 in MeOH (20 ml) is stirred at room temperature for 72 hours. The reaction mixture is evaporated to dryness in vacuo to yield a white solid. The white solid is suspended in diethyl ether before filtration and drying to yield ((S)-4-Amino-4-carbamoyl-butyl)-carbamic acid benzyl ester.
