반응 단계
Following the same general procedure described previously for cinnamoyl-glycine-methyl ester, glycine-t-butyl ester. MCl (10.88 grams) was dissolved in dimethyl formamide (approximately 100 ml), cooled to 0° C. and treated with N-methylmorpholine (9.04 ml, 1 equivalent) followed immediately by a pre-cooled solution of benzoic acid (7.94 grams) in ethyl acetate (approximately 75 ml) which had been pre-activated by treatment with N-methylmorpholine (9.04 ml) followed by isobutyl chloroformate (8.4 ml) at -20° C. After work-up, benzoyl-glycine-t-butyl ester was obtained as a white solid which was used for the next step without further purification.
