Reaction Steps

After dissolving the 3-fluorocatechol (30 g, 0.234 mol) in dimethylformamide (400 ml), methyl iodide (32 ml, 0.515 mol) and potassium carbonate (80.7 g, 0.515 mol) were added while stirring on ice, and the stirring was continued at room temperature for 18 hours. Water (500 ml) was added and extraction was performed with diethyl ether (400 ml×2), and then after washing the combined organic layers with brine (400 ml) and drying over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure to yield the title compound as a light yellow liquid (34 g, 93%).
