Procedure

To a solution of N-(3,4-dichlorophenyl)-2-(3-hydroxyphenyl)acetamide (5.5 g, 0.019 mol) in DMF (25 ml) was added potassium carbonate powder (3.93 g, 0.028 mol). To the flask was added benzyl bromide (2.37 ml, 0.021 mol). The reaction was allowed to stir overnight. Solvent was removed and the reaction was diluted with ethyl acetate. The organic layer was washed with water, dried over MgSO4, filtered and concentrated. The crude product was triturated with ether and hexanes to provide the title compound (4.65 g, 64% yield): ES-MS (m/z) 386 [M+H]+.
