Participants

Reaction Steps

3-Cyano-3-{3-cyclohexyl-2-[(morpholine-4-carbonyl)-amino]-propionylamino}-pyrrolidine-1-carboxylic acid benzyl ester (0.1 g, 0.20 mmol, 1.0 equiv) was dissolved in 15 mL of absolute EtOH. 10% Pd on carbon (20 mg) was added and the mixture was stirred under 1 atm of H2 until the starting material disappeared by TLC (5% MeOH in CH2Cl2. The crude mixture was filtered on diatomaceous earth and the filtrate was concentrated. The crude material was purified by reverse-phase HPLC to give two diastereomers; MS, m/z 378=M+1.
