To a stirring solution of 3-bromo-6-methoxy-2-(methoxymethoxy)phenol (12 g, 0.045 mol) in acetonitrile (100 mL) at 0° C. was added potassium carbonate (18 g, 0.135 mol) and cyclopropylmethyl bromide (9 g, 0.067 mol) and the resultant reaction mixture was stirred for 1 h at RT. The reaction mixture was filtered through celite and the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, 0-12% ethyl acetate in pet ether) to afford 1-Bromo-3-(cyclopropylmethoxy)-4-methoxy-2-(methoxymethoxy)benzene as a solid (5.5 g, 38%).
