Participants

Reaction Steps

0.50 g of methyl iodide was added to a mixture of 0.20 g of 3-ethylsulfonyl-N-(3,5-bistrifluoromethylphenyl)picolinamide (Compound of Present Invention 14), 0.12 g of potassium carbonate and 3 mL of acetone, and the mixture was stirred at room temperature for 1 hour. 1 mL of DMF was added to the reaction mixture, and the mixture was stirred at 60° C. for 2 hours. Water was added to the reaction mixture cooled to room temperature, 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 0.18 g of 3-ethylsulfonyl-N-methyl-N-(3,5-bistrifluoromethylphenyl)picolinamide (hereinafter, referred to as Compound of Present Invention 38).
