実験手順

To a suspension wherein 5-amino-1-(6-bromo-1,1,3,3-tetrafluoro-1,3-dihydroisobenzofuran-5-yl)-3-cyanopyrazole (754 mg, 2.00 ml), sodium trifluoromethane-sulfinate (406 mg, 2.60 mmol) and dimethylamine tosylate (652 mg, 3.00 mmol) are in toluene (5 ml), thionyl chloride (309, mg, 2.60 mmol) was added dropwise under ice cooling over a period of about 10 minutes and then stirred under heating at 50 to 60° C. for 10 hours. After allowing time to cool, the reaction solution was poured into water, extracted with ethyl acetate, and the organic layer was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was subjected to silica gel column chromatography to give 200 mg of 5-amino-1-(6-bromo-1,1,3,3-tetrafluoro-1,3-dihydroisobenzofuran-5-yl)-3-cyano-4-trifluoromethylsulfinylpyrazole.
