Reaction Steps

33 g of 3-chloro-4-trifluoromethylbenzylhydrazine were added dropwise, under nitrogen, to a solution of 23.5 g of β-amino-β-ethoxyacrylic acid ethyl ester and a pinch of p-toluenesulphonic acid in 100 ml of ethanol. After stirring overnight, the product which had precipitated was filtered off and recrystallised from ethanol. Melting point: 83°, 24 g (56%).
