To a solution of 4-iodophenol (1.0 g) in acetonitrile (10 mL), cesium carbonate (3.0 g) and 1-bromo-2-chloroethane (0.8 g) were added and the mixture was heated to 100° C., at which it was stirred for 4 hours. Additional 1-bromo-2-chloroethane (1.0 g) was further added and stirred at 100° C. for 4 hours. The reaction mixture was cooled to room temperature and filtered to remove insoluble materials, and the filtrate was concentrated under reduced pressure. The resulting residue was purified by NH-type silica gel column chromatography (eluting solvent: n-hexane:ethyl acetate=11:1) to give the titled compound (0.87 g, 68%) as a yellow oil.
