Reaction Steps

A solution of triphenylphosphine (0.983 g) and carbon tetrachloride (0.145 ml) in anhydrous dichloromethane (5 ml) at 0° C. was stirred for 5 minutes. 3-Cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-formylpyrazole (0.25 g) was then added and the mixture was heated under reflux for 5 hours and then evaporated. The residue was purified by column chromatography on silica gel eluting with dichloromethane. Combination and evaporation of suitable fractions gave the title compound as a white solid, m.p. 99-101° C.
