Reaction Steps

A mixture of tert-butyl α-(1-azidomethyl)-3-(2-methylpropyl)-2-oxo-1-(2-phenylethyl)-3-pyrrolidineacetate (648 mg, 1.56 mmol) and 10% palladium on carbon (163 mg) in EtOH (25 mL) is hydrogenated at 30 psi in a Parr flask for 16 hours. The mixture is filtered, rinsing the residual solids with MeOH and CH2 Cl2. The filtrate is concentrated and purified by silica gel chromatography (15 g SG; EtOAc, 15% MeOH/EtOAc) to provide 356 mg (57%) of the title compound as a partially crystalline solid:
