Reaction Steps

17.3 g (0.05 mol) of L-alanyl-L-phenylalanine ethyl ester·HBr was suspended in 250 ml of dichloromethane, and to this susension were added 5.1 g (0.05 mol) of triethylamine and 9 g (0.05 mol) of p-acetoxybenzoic acid, and then 9.6 g (0.05 mol) of 1-ethyl-3(3-dimethylaminopropyl)carbodiimide·HCl was added in an ice bath. This mixture was stirred for three hours, and then was washed with a 0.1% aqueous solution of Na2CO3 and with a 0.1 N HCl solution three times and then with distilled water three times, and was dried over anhydrous sodium sulfate. Dichloromethane was removed from the dried mixture under reduced pressure to obtain p-acetoxybenzoyl-L-alanyl-L-phenylalanine ethyl ester.
