Reaction Steps
To a suspension of sodium hydride in DMF (50 ml) at 0° C. was added dropwise a solution of methyl 3-(4-hydroxyphenyl)propionate (10.0 g, 55.5 mmol) and benzyl bromide (7.93 ml, 66.7 mmol) dissolved in DMF (100 ml). The mixture was stirred at room temperature for 16 hours, cooled to 0° C., quenched with aqueous ammonium chloride (50 ml) and extracted with ethyl acetate (2×150 ml). The combined organic layers were washed with aqueous ammonium chloride (50 ml), brine (3×60 ml), dried over sodium sulfate and concentrated in vacuo. The residue was crystallized from hexane-ethyl acetate to give the title compound (13.7 g, 91%) as a white solid.
