Reaction Steps
A mixture of 3-bromo-2-chloro-5-nitropyridine (0.237 g, 1 mmol), 2,4-difluorophenol (0.13 g, 1 mmol) and cesium carbonate (0.326 g, 1 mmol) in dimethyl sulfoxide (2 mL) was reacted in a Biotage microwave reactor at 80° C. for 30 minutes. The reaction mixture was partitioned between ethyl acetate and water, washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered and concentrated. The residue was purified by flash chromatography (silica gel, 0-20% ethyl acetate in heptanes) to provide 0.312 g (94%) of the title compound.
