Reaction Steps
18 g of 3-n-butoxybenzylhydrazine were added dropwise, under nitrogen, ot a solution of 14.8 g of β-amino-β-ethoxyacrylic acid ethyl ester and a pinch of p-toluenesulphonic acid in 180 ml of ethanol. After stirring for 2 hours, the mixture was left to stand overnight. The compound identified above, which had separated out as a precipitate, was filtered off and recrystallised from ethanol. Melting point: 110°, 8 g (33%).
