Reaction Steps

To a solution of 2-chloro-4-methylphenol (500 mg, 3.62 mmol) in acetonitrile (20 mL) was added 1,2-dibromoethane (3.29 g, 17.53 mmol) followed by cesium carbonate (2.28 g, 7.01 mmol). The resulting mixture was heated at 85° C. for 48 h, then cooled to rt. The solution was filtered through a Celite® pad. The Celite® was washed with acetone and the combined eluents were concentrated under reduced pressure to give the title compound as a white solid (697 mg, 76%). GC/MS (EI) m/z 248 (M)+, RT 7.33 min.
