A solution of 2.95 g of 2(R)-[1(S)-(tert-butoxycarbonyl)-4-phenylbutyl]-2′-[N-(benzyloxycarbonyl)-glycinyl]-4-methylvalerohydrazide in 30 ml of methanol was hydrogenated in the presence of 0.300 g of 5% palladium-on-carbon for 0.5 hours. The mixture was filtered and evaporated to give 2.2 g of 2(R)-[1(S)-(tert-butoxycarbonyl)-4-phenylbutyl]-2′-glycinyl-4-methylvalerohydrazide in the form of a white foam.
