Reaction Steps
59 g of 4-chloro-3-methoxybenzylhydrazine were added dropwise, under nitrogen, to a solution of 50.5 g of β-aminoβ-ethoxyacrylic acid ethyl ester and 1.5 g of p-toluenesulphonic acid in 250 ml of ethanol. After standing overnight, the compound identified above, which had separated out as a precipitate, was filtered off and recrystallised from ethanol. Melting point: 148°, 30 g. (38%).
