Reaction Steps

A mixture of 0.28 g of 2-(3-fluoropyridin-4-yl)-5-(trifluoromethyl)benzoxazole, 0.15 g of 1-propanethiol, 0.40 g of potassium carbonate and 2 ml of DMF was stirred while heating at 50° C. for one hour. The reaction mixture was cooled to room temperature, and then water was added to the reaction mixture, which was extracted with ethyl acetate. The organic layer was washed with a saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.30 g of 2-(3-propylthiopyridin-4-yl)-5-(trifluoromethyl)benzoxazole (hereinafter, referred to as “active compound 42”).
