0.78 g of {[2-{2-(S)-[Benzyloxy-carbonyl]-pyrrolidine-1-yl}-1-(R)-(4-methoxybenzyl)-2-oxo-ethyl]-tert.-butoxycarbonyl-amino}-acetic acid ethyl ester were dissolved in 50 mL of methanol and hydrogenated for 3 h at room temperature using 0.4 g palladium on charcoal (10%) as catalyst. Filtration followed by concentration in vacuo affords 0.58 g (89%) of the title compound as a colorless oil. (−)-APCI-MS: 477 ([M-H]−).
