A solution of 6-bromo-2,3-difluorobenzoic acid (7.66 g, 32.3 mmol), methyl iodide (10 mL, 160 mmol) and potassium carbonate (5.36 g, 38.8 mmol) in N,N-dimethylformamide (30 mL) was stirred at room temperature for 1 hour. The solution was poured into water, and organic matter was extracted with ethyl acetate. The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the title compound (8.11 g, 100% yield).
