Participants

Reaction Conditions

Reaction Steps

3-Chloropyridin-4-ol (0.259 g), 1-fluoro-3-(trifluoromethyl)benzene (0.126 mL) and potassium carbonate (0.276 g) were suspended in N-methyl-2-pyrrolidone (1.2 mL), and the suspension was stirred at 150° C. for 2 hr. The reaction mixture was cooled to room temperature, diluted with water, extracted with ethyl acetate, dried over anhydrous magnesium sulfate, filtered, concentrated, and purified by silica gel column chromatography (ethyl acetate/hexane→methanol/ethyl acetate) to give the title compound (28.1 mg).
