Reaktionsschritte
A mixture of 3-bromo-4-fluorobenzotrifluoride (0.5 mL, 3.52 mmol), 2,4-difluorophenol (0.337 mL, 3.52 mmol), and potassium carbonate (0.486 g, 3.52 mmol) in dimethylformamide (7 mL) was heated at 80° C. overnight. The reaction mixture was cooled to ambient temperature and partitioned between ethyl acetate and water. The layers were separated, and the aqueous layer was extracted with ethyl acetate. The combined organics were washed with water and saturated aqueous sodium chloride, dried over anhydrous sodium sulfate, filtered, and concentrated by rotary evaporation. The crude material was purified by flash chromatography (ethyl acetate/hexanes) to provide the title compound (1.0 g, 80% yield).
