Reaction Steps
1-(2-(R)-Acetylamino-3-biphenyl-4yl-propionyl)-pyrrolidine-2-(S)-carboxylic acid benzyl ester (0.50 g) were dissolved in 30 mL of methanol and hydrogenated for 4 h at room temperature using 0.3 g palladium on charcoal (10%) as catalyst. Filtration followed by concentration in vacuo affords 0.37 g (91%) of the title compound as a white solid. (+)-APCI-MS: 381 (MH+).
