Dimethylformamide → HCID 86651042, compound

Participants

Reaction Steps

To a mixture of 0.28 g of 2-(3-fluoropyridin-4-yl)-5-(trifluoromethyl)benzoxazole, 0.50 g of potassium carbonate and 2 ml of DMF, 0.15 g of 2,2,2-trifluoroethanethiol was added. The reaction mixture was stirred at room temperature for 1.2 hours. Water was added to reaction mixture, which followed by extraction with ethyl acetate twice. The combined organic layers were washed with 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 0.32 g of 2-[3-(2,2,2-trifluoroethylthio)pyridin-4-yl]-5-(trifluoromethyl)benzoxazole (hereinafter, referred to as “active compound 46”).
