Participants

Reaction Conditions

Reaction Steps

0.37 g of m-chloroperbenzoic acid (purity of 68%) was added to a mixture of 0.23 g of 3-ethylsulfanyl-N-methyl-N-(5-trifluoromethylsulfanylpyridin-2-yl)picolinamide (Compound of Present Invention 32) and 5 mL of chloroform under ice cooling, and the mixture was stirred at 0° C. for 2 hours. A saturated aqueous sodium bicarbonate solution and a saturated aqueous sodium thiosulfate solution were poured to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure, and the resulting residue was applied to a silica gel column chromatography to obtain 0.20 g of 3-ethylsulfonyl-N-methyl-N-(5-trifluoromethylsulfanylpyridin-2-yl)picolinamide (hereinafter, referred to as Compound of Present Invention 33).
