To a solution 2-bromo-6-fluorobenzoic acid (50 g, 0.229 mol) and potassium carbonate (31.6 g, 0.229 mol) in N,N-dimethylformamide (250 mL) was added dropwise methyl iodide (51.83 g, 0.365 mol) over a 30 minute period. The reaction mixture was stirred at RT for 3.5 hours. The resulting mixture was diluted with water (500 mL) and extracted with EtOAc (3×300 mL). The combined organic layers were washed with 1M aqueous HCl (100 mL), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure to give the title compound (53 g, 99.7%).
