Reaction Steps

To a suspension of 4-bromo-3-fluorophenol (2.87 g) and cesium carbonate (12.2 g) in N,N-dimethylformamide (30 mL) was added methyliodide (1.87 mL) at room temperature, and the mixture was stirred at room temperature overnight. The reaction mixture was poured into water, and the resulting mixture was extracted with diethyl ether. The extract was washed with water and brine successively, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure to give 1-bromo-2-fluoro-4-methoxybenzene (3.02 g).
