An atmosphere of hydrogen is placed over a mixture of N-benzyloxy-α-methyl-3-(2-methylpropyl)-2-oxo-1-(2-phenylethyl)-3-pyrrolidineacetamide (80.0 mg, 0.189 mmol), MeOH (4.5 mL) and Pearlman's catalyst (15 mg). The mixture is stirred at room temperature for 4 hours. The mixture is filtered, the solids rinsed with MeOH (4×5 mL), and the filtrate concentrated to give 55.9 mg of an oil. Crystallization from hexane provided 46.9 mg (75%) of the title compound as a white solid (mp 107°-108° C.).
