To 200 ml of N,N-dimethylformamide, were added 17 g of crotonamide, 105 g of LEVATIT MP-500, which was also used in Example 68, and 32 g of benzylchloride. They were reacted at 50° C. for 4 hours with stirring. After the reaction, the reaction solution was treated in the same manner as in Example 69, the resulting distillation residue was recrystallized from benzine, and 25 of N-benzylcrotonamide having a melting point of 112.5°-113.6° C. was obtained (yield: 71%).
