Reaction Steps
A mixture of 0.19 g of 3-fluoro-4-[5-(trifluoromethyl)benzofuran-2-yl]pyridine, 0.19 g of potassium carbonate and 3 ml of methanol was heated under reflux for 27 hours. To this mixture was added 93 mg of potassium carbonate, and the mixture was further heated under reflux for 2 hours. The reaction mixture was cooled to room temperature. Water was added to the reaction mixture, and the mixture was extracted twice with ethyl acetate. The organic layers were combined and washed with saturated brine and dried over magnesium sulfate, then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 0.16 g of 3-methoxy-4-[5-(trifluoromethyl)benzofuran-2-yl]pyridine (hereinafter, referred to as “Present Active Compound 9”).
