Reaction Steps

A mixture of 4-fluorobenzoic acid (4.9 g, 35.3 mmol), benzyl bromide (3.8 mL, 31.7 mmol), and cesium carbonate (17.2 g, 53 mmol) in DMF (50 mL) at room temperature was stirred for 24 hours, diluted with water, and extracted with diethyl ether. The combined extracts were washed with brine, dried (MgSO4), filtered, and concentrated to provide the desired product. MS (DCI) m/e 248 (M+H)+.
