実験手順

112 mg of 6-methanesulfonyl-pyridin-3-ol and 100 mg of potassium carbonate were added to an N-methylpyrrolidinone (3 ml) solution of 135 mg of 2,3,4-trifluoro-nitrobenzene, and the reaction liquid was stirred at 50° C. for 1 hour. The reaction liquid was diluted with ethyl acetate, washed with water and saturated saline in order, and dried with anhydrous sodium sulfate. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through silica gel column chromatography (developing solvent: hexane/ethyl acetate=1/1) to obtain the entitled compound.
