Reaction Steps
26.6 g of 2,5-dimethylbenzylhydrazine were added dropwise to a solution of 28.2 g of β-amino-β-ethoxyacrylic acid ethyl ester and 1 g of p-toluenesulphonic acid in 130 ml of ethanol, in the course of which the temperature rose from 25° to 35° C. After stirring overnight, the compound identified above separated out, and was filtered off and recrystallised from ethanol. Melting point: 124°, 20 g (52%).
