Reaktionsschritte

To a suspension of sodium hydride (60%, 1.09 g) in 1,2-dimethoxyethane (25 mL) was added 2-(4-bromophenyl)ethanol (5 g) under ice-cooling, and the mixture was stirred at room temperature for 1.5 hours. To the reaction mixture was added benzyl bromide (3.25 mL), and the mixture was stirred at 80° C. overnight. To the reaction mixture was added a saturated aqueous ammonium chloride solution, and the resulting mixture was extracted with diethyl ether. The extract was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane-n-hexane/ethyl acetate=50/1-20/1) to give the title compound (6.8 g).
