Reaction Steps

A mixture of 0.28 g of 2-(3-fluoropyridin-4-yl)-5-(trifluoromethyl)benzoxazole, 0.10 g of 1H-1,2,4-triazole, 0.55 g of potassium carbonate and 2 ml of DMF was stirred while heating at 50° C. for 1.5 hours. Then, the reaction mixture was cooled to room temperature. Water was added to the reaction mixture, followed by extraction with ethyl acetate twice. The combined organic layers were washed with a saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.26 g of 2-[3-(1,2,4-triazole-1-yl)pyridin-4-yl]-5-(trifluoromethyl)benzoxazole (hereinafter, referred to as “active compound 63”).
