To a solution of 4-bromo-1-chloro-2-(chloromethyl)benzene (12.2 g, 50.85 mmol) and phenol (4.79 g, 50.85 mmol) in DMF (102 mL) under nitrogen atmosphere, K2CO3 was added (35.14 g, 254.25 mmol). The resulting mixture was stirred at r.t. for 18 h. After completion of the reaction as confirmed by TLC, the reaction mixture was passed through celite plug and the filterate was evaporated. The residue obtained was dissolved in ethyl acetate (100 mL) and washed with water (2×100 mL) and brine (2×100 mL) successively. The organic layer was dried over Na2SO4 and concentrated in vacuo to afford crude product which was purified by column chromatography (silica gel, 1:9 Ethyl acetate:Pet. Ether) to afford the title compound (14.7 g, 97.3%).
