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
