A mixture of methyl 4-fluoro-3-methoxybenzoate (2.13 g), 4-bromo-1H-imidazole (3.74 g) and potassium carbonate (4.80 g) in DMF (20 mL) was stirred at 100° C. overnight, and allowed to cool to room temperature, and ethyl acetate and water were added. The organic layer was separated, washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (0.580 g).
