実験手順

To a solution of benzyl 3-(N-tertiarybutoxycarbonyl-L-phenylalanyl)oxy-15-methylhexadecanoate (2.85 g) in methanol (50 ml) was added 10% palladium on active carbon (0.5 g) and water (5 ml). The mixture was stirred at room temperature under hydrogen atmosphere for 1 hour. The catalyst was filtered off and the solvent was removed under reduced pressure to give 3-(N-tertiarybutoxycarbonyl-L-phenylalanyl)oxy-15-methylhexadecanoic acid as an oil (2.31 g).
