Reaction Steps
A solution of 45 g of m-iodobenzylhydrazine in 70 ml of ethanol was added dropwise to a solution of 28.6 g of β-amino-β-ethoxyacrylic acid ethyl ester and 1.5 g of p-toluenesulphonic acid in 350 ml of ethanol. After stirring overnight, the compound identified above had separated out as a precipitate and was filtered off and recrystallised from ethanol. Melting point: 186°, 16 g (28%).
