Procedure
To a solution of potassium carbonate (0.63 g, 4.5 mmol) in dimethylformaide (10 mL) was purged with nitrogen for 10 min at 75° C. 4-iodophenol (0.55 g, 2.5 mmol) was added to the mixture and the solution was purged with nitrogen for additional 10 min. To the reaction mixture 1-(trityloxy)propan-2-yl methanesulfonate (1.00 g, 2.53 mmol) was added and stirred for 24 hours at the same temperature. The reaction mixture was diluted with water (20 mL) and extracted with ethyl acetate (20 mL*3). The combined organic layer was dried over sodium sulfate and concentrated. The crude product was purified by combiflash silica gel chromatography (petroleum ether:ethyl acetate=10:1) to give the title compound (600 mg, 46%) as colorless oil.
