Procedure

31.5 g of 3-trifluoromethyl-4-methylbenzylhydrazine were added dropwise under nitrogen to a solution of 35.3 g of α-phenyl-β-amino-β-ethoxyacrylic acid ethyl ester and 1 g of p-toluenesulphonic acid in 150 ml of ethanol. After stirring overnight,the solvent was distilled off in vacuo and the residue was recrystallized from dimethylformamide.

Workup

  1. distillationthe solvent was distilled off in vacuo
