Reaktionsschritte

The process of Example 51 was repeated except that 357 mg (1.00 mmol) of N-benzyloxycarbonyl-(β-benzyl)-L-aspartic acid and 431 mg (2.00 mmol) of D,L-phenylalanine methyl ester hydrochloride were reacted. As a result, a 238 mg amount (yield of 45.8%) of N-benzyloxycarbonyl-(β-benzyl)-L-aspartyl-L-phenylalanine methyl ester having an [α]D20 = -13.2 (C=1.0 dimethylformamide) was obtained.
