Procedure

To a solution of 4-iodophenol (20.0 g) and 1-bromo-3-chloropropane (18.6 g) in 2-butanone (200 mL), potassium carbonate (25.1 g) was added and stirred at 100° C. for 5 hours. The reaction mixture was cooled to room temperature, diluted with water and extracted with ethyl acetate. The organic layer was washed with water and brine, dried over sodium sulfate and concentrated under reduced pressure to give the titled compound (28.4 g) as an orange-colored oil.
