To a stirred solution of 1-(3-chloro-4-hydroxylphenyl)ethanone (1.7 g, 10 mmol) in DMF was added K2CO3 (1.52 g, 11 mmol), 2 N NaOH solution (5 ml), and Mel (0.68 ml). The reaction mixture was stirred at room temperature for 2 hours. Another 1.24 ml of Mel was added, and the reaction mixture was stirred for an additional 30 minutes. Water (50 ml) was added, and the product was extracted with 200 ml of EtOAc and 100 ml of benzene. The organic layer was washed with brine (50 ml), and dried with MgSO4, and the solvent was removed in vacuo to give the title compound in quantitative yield.
