Reaction Steps
N-t-butoxycarbonyl-prolyl-phenylalanyl-glycine was synthesized from N-t-butoxycarbonyl-prolyl-phenylalanyl-glycine ethyl ester in the same manner as described in Example 1 in yield of 89.8%. Crystals obtained by recrystallization from ethyl acetate and petroleum ether had a melting point of 98°-100° C. and Rf=0.67 (TLC, chloroform: methanol: acetic acid=95:5:3 by volume).
