Versuchsvorschrift
The procedure of Example 9 was followed excepting that: the quantity of N-benzoyl-L-aspartic acid was 2.85 g (10 mmol) and of the L-phenylalanine methyl ester was 2.69 g (15 mmol), in place of polyethylene glycol 600, polyethylene glycol 200 was used, the reaction time was 7 hours. N-benzoyl-L-aspartyl-L-phenylalanine methyl ester was obtained in the yield of 64.2%.
