Reaction Steps

Boc-Glu(OTce)-OBzl (0.50 g) was hydrogenated in ethanol (25 ml) with 10% palladium on carbon (0.10 g). The catalyst was filtered off and the filtrate was evaporated. The residue was extracted with ethyl acetate. The organic layer was washed successively with 2% hydrochloric acid, water and saturated sodium chloride, dried over magnesium sulfate and evaporated. The residue was pulverized with petroleum ether, filtered and dried to give Boc-Glu(OTce)-OH (0.30 g).
