Versuchsvorschrift

Example 17 was repeated except for using DL-phenylalanine methyl ester instead of L-phenylalanine methyl ester to obtain 756 mg of an addition compound of N-benzyloxycarbonyl-L-aspartyl L-phenylalanine methyl ester and D-phenyl alanine methyl ester (1:1) (melting point: 105° to 111° C.; yield: 62.3% based on N-benzyloxycarbonyl L-aspartic acid).
