Procedure

An aliquot of the above solution of step A containing approximately two millimoles of 3,3-bis-ethoxy-2-(3-trifluoromethylbenzoyl)acrylonitrile was reacted with 0.49 g (2.0 mmol) of 2,6-dichloro-4-trifluoromethylphenylhydrazine in 10 mL of ethanol under reflux overnight. The cooled mixture was poured into dilute hydrogen chloride (HCl) and the product was extracted into ethyl acetate (EtOAc), washed with water and brine, and dried over magnesium sulfate (MgSO4). Chromatography on silica gel with 4:1 hexane/EtOAc gave the title product, 320 mg (31%), m.p. 77°-78° C. from pentane.
