Reaction Steps

A solution of 2,6-dichloro-4-trifluoromethylphenylhydrazine (10 g) and ethyl 2-cyano-3-ethoxyacrylate (7.0 g) in absolute ethanol (200 ml) was heated under reflux with stirring for 24 hours. Evaporation of solvent and recrystallisation from diisopropyl ether gave ethyl 5-amino-l-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole-4-carboxylate, m.p. 131°-134°.
