Reaction Steps

0.2 g of [[3-(benzyloxy)phthalimido]methyl][(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid was dissolved in 50 ml of methanol containing 0.1 g of 10% palladium-on-charcoal. The mixture was hydrogenated for 4 hours and then filtered. The filtrate was evaporated to give 0.16 g of [(3-hydroxyphthalimido)methyl][(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid in the form of an off-white foam.
