Condensation of glycine benzyl ester hydrochloride (I) and p-nitrobenzoyl chloride in benzene yielded p-nitrobenzoylglycine benzyl ester (II) which was catalytically reduced to the objective p-aminohippuric acid (III). The same condensation of glycine benzyl ester with p-nitrobenzoyl chloride gave benzyl p-nitrobenzoate (V). In a similar manner, glycine ethyl ester, either as the free ester or as a hydrochloride, yielded p-nitrobenzoyl-glycine ethyl ester.
