実験手順

A mixture of 4-iodophenol (15.0 g, 68.2 mmol) and 1,2-dibromoethane (50 ml, 580 mmol) and potassium carbonate (14.0 g, 0.1 mol) was stirred and refluxed for 22 h. After cooling to r.t., the mixture was filtered, washed with ethyl acetate and concentrated in vacuo. The residue was chromatographed on silica gel (Hexane/ethyl acetate 40: 1 to 20:1) to afford the title compound (18.7 g, 84%) as a white solid.
