Procedure

Potassium butoxide (0.5 g) was added to a THF (10 mL) solution of allyl 2-{3-(2,6-difluorophenyl)pyrazol-1-yl}acetate (0.5 g) and 5-chloro-1-methyl-3-trifluoromethylpyrazole-4-carbonyl chloride (0.44 g) at 0° C. and stirred for 5 minutes. Water (5 ml) was added thereto, and then extracted with diluted hydrochloric acid and ethyl acetate. After the organic layer was dried over anhydrous magnesium sulfate, and then concentrated, and the resulting concentrate was purified through silica gel column chromatography (chloroform) to obtain the intended product, Compound No. I-133 (0.89 g).
