| Reactant | 2-Propenoic acid, 2-cyano-3-ethoxy-, ethyl ester | HCID 78943 | — |
| Reactant | 2-nitro-4-(trifluoromethyl)phenylhydrazine | HCID 3838097 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | HCID 67795583 | HCID 67795583 | — |
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°.
