Reaction Steps

4-Trifluoromethyl-2-nitrophenylhydrazine (13.5 g) and ethyl 2-cyano-3-ethoxyacrylate (10.3 g) were heated under reflux in ethanol (300 ml) for 24 hours. The solvent was removed under reduced pressure and the resulting residue triturated with dichloromethane/hexane to give ethyl 2-cyano-3-(2-nitro-4-trifluoromethylphenylhydrazino)acrylate, m.p. 163°-164°.
