Procedure

To a stirred solution of Ethyl 2-(3-hydroxyphenyl)acetate (3 g, 16.6 mmol) in DMF (25 ml) was added potassium carbonate (2.99 g, 21.6 mmol) at room temperature followed by drop wise addition of benzyl bromide (3.13 g, 18.3 mmol). The reaction mixture was stirred for 16 hours and taken in ethyl acetate, washed with water (2×) and brine. The organic layer was dried over Na2SO4, filtered, concentrated and purified by flash chromatography on a silica gel column (hex:ethyl acetate 4:1) to give the title compound.
