To a solution of 4-bromobenzyl alcohol (2.8 g) and diisopropylethylamine (2.5 g) in dichloromethane (30 mL) was added chloromethyl methyl ether (1.3 g) at 0° C., and the mixture was stirred at room temperature for 14 hours. To the reaction mixture was water, and the mixture was extracted diethyl ether. The organic layer was washed with water and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: hexane/ethyl acetate=5/1) to give 1-bromo-4-[(methoxymethyloxy)methyl]benzene (3.0 g).
