Procedure

To a stirring suspension of sodium hydride (1.2 g, 52.1 mmol, 60% dispersion in mineral oil) in DMF (75 mL) at 0° C. was added 2-bromophenol (6.0 g, 34.7 mmol) dropwise. After stirring for 20 min, bromomethyl methyl ether (4.3 g, 34.7 mmol) was added. After stirring for 16 h at room temperature, the mixture was poured into water (250 mL) and extracted with hexane. The organic layer was washed with brine, dried (MgSO4), filtered and concentrated. The residue was purified by column chromatography (silica gel, hexane) to yield the title compound as a colorless oil (4.0 g, 53%). 1NHMR (400 MHz, CDCl3) δ 7.55 (d, 1H), 7.28 (t, 1H), 7.16 (d, 1H), 6.91 (t, 1H), 5.25 (s, 2H), 3.54 (s, 3H).
