Reaction Steps
To a solution of Boc-Glu-OBzl (1.00 g) and TceOH (0.53 g) in methylene chloride (15 ml) were added 4-dimethylaminopyridine (0.04 g) and WSC.HCl (0.57 g) successively under ice cooling. The mixture was stirred for 3 hours at the same temperature. After evaporation, the residue was extracted with ethyl acetate. The organic layer was washed successively with 2% hydrochloric acid, water, 2% sodium hydrogencarbonate solution, water and saturated sodium chloride solution, and dried over magnesium sulfate. The evaporated residue was crystallized with petroleum ether, filtered and dried to give Boc-Glu(OTce)-OBzl (1.01 g).
