Reaction Steps

A solution of 0.160 g of (E)-N-(1,2,3,5,6,7,8,8a(RS)-octahydro-1,3-dioxoimidazo[1,5-a]pyrazin-2-yl)-2(R)-[1(S)-(benzyloxycarbamoyl)-4-phenyl-3-butenyl]-4-methylvaleramide in 10 ml of methanol was hydrogenated for 3 hours in the presence of 0.02 g of 10% palladium-on-carbon. The catalyst was removed by filtration and evaporation of the solvent gave 0.120 g of N-(1,2,3,5,6,7,8,8a(RS)-octahydro-1,3-dioxoimidazo[1,5-a]pyrazin-2-yl)-2(R)-[1(S)-(hydroxycarbamoyl)-4-phenylbutyl]-4-methylvaleramide in the form of a white solid.
