Procedure

(3-Bromophenyl)methanol (500 mg) was mixed with DMF (10 ml), and sodium hydride (55% suspended in oil) was added thereto at 0° C., followed by stirring for 10 minutes under ice-cooling. 1-(Chloromethyl)-4-methoxybenzene (520 mg) was added to the reaction mixture, followed by stirring at room temperature for 2 hours. Water and EtOAc were added to the reaction mixture, and the organic layer was dried over MgSO4 and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (CHCl3/hexane) to obtain 1-bromo-3-{[(4-methoxybenzyl)oxy]methyl}benzene (801 mg).
