Reaction Steps

432 mg (3.22 mmol) of 2-(2-ethoxyethoxy)ethanol was dissolved in 40 ml of dichloromethane, and 0.6 ml (4.19 mmol) of triethylamine and 614 mg (3.22 mmol) of p-toluenesulfonyl chloride were added thereto. The mixture was stirred at room temperature for 15 hours. After the solvent was removed under reduced pressure, 40 ml of water was added thereto. The mixture was extracted with 30 ml of ethyl acetate. The solvent was removed under reduced pressure to give 760 mg (2.64 mmol) of the title compound in a yield of 82%.
