To a stirring solution of 4-bromo-2-methoxy-3-(methoxymethoxy)phenol (600 mg, 2.28 mmol) in acetonitrile (20 mL) was added potassium carbonate (944 mg, 6.84 mmol) and ethyl iodide (711 mg, 4.56 mmol) and the resultant reaction mixture was heated to 70° C. for 3 h. The reaction mixture was filtered through celite and the filtrate was concentrated under reduced pressure. The obtained residue was purified by column chromatography (silica gel, 0-7% ethyl acetate in pet ether) to afford 1-Bromo-4-ethoxy-3-methoxy-2-(methoxymethoxy)benzene as a solid (525 mg, 79%).
