Reaction Steps

To a solution of methyl 3-chloro-2-ethenyl-5-[4-(1H-pyrazol-1-yl)benzyl]-4-(trifluoromethyl)benzoate (0.80 g) and ethyl 3-chloro-2-ethenyl-5-[4-(1H-pyrazol-1-yl)benzyl]-4-(trifluoromethyl)benzoate (0.80 g) in THF (5.08 mL)-water (5.08 mL) were added lithium hydroxide monohydrate (0.20 g) and methanol (0.50 mL), and the mixture was stirred at 15° C. for 16 hr. The reaction mixture was poured into 1N hydrochloric acid, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (0.15 g).
