Reaction Steps

A mixture of 2-bromo-1-fluoro-4-nitrobenzene (2.20 g, 10 mmol), 4-hydroxybenzonitrile (1.31 g, 11 mmol), and cesium carbonate (3.58 g, 11 mmol) in DMSO (20 mL) was heated at 90° C. for 2 hours. After cooling, the reaction mixture was partitioned between water and ethyl acetate. The aqueous layer was extracted three times with ethyl acetate. The combined organic layers were washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered, and concentrated to give 3.19 g (110%) of the title compound.
