In 69.2 g of pyridine was dissolved 33.27 g of 2-benzyloxy-ethanol, and to this solution was then added with stirring 45.9 g of p-tosyl chloride at an inner temperature in the range of 5°- 10° C. The resulting mixture was stirred at a temperature of 15° C for 2 hours. After completion of the reaction, a mixture solution of 130 ml of conc. hydrochloric acid and 450 ml of ice-water was added to the resulting reaction mixture and then subjected to extraction with benzene. The extract was washed with a saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. Upon evaporation of the solvent from the extract, there was obtained 66.9 g of 2-benzyloxy-1-(p-toluenesulfonyloxy)ethane as an oil.
