反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 35 g (10% excess) of β-amino-β-ethoxyacrylic acid ethyl ester are introduced into 100 ml of ethanol. 32 g of 3-chlorobenzylhydrazine in 50 ml of ethanol are added while stirring. The mixture is worked up as above. 18.9 g of the compound identified above, as colorless felted needles of melting point 132°, are obtained. (Yield: 42% of theory) are obtained
