Procedure

To a solution of cyclohexanol (0.275 g) in N,N-dimethylformamide (5 mL) was added sodium hydride (60%, 0.069 g). After 30 minutes, 2-bromo-6-fluorobenzonitrile (0.500 g) was added and the reaction stirred at room temperature for 2 hours. The reaction mixture was diluted with ethyl acetate (25 mL), washed with water (20 mL) and brine (20 mL), dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography eluting with a gradient of 3% to 10% ethyl acetate/hexanes provided the title compound.
