الإجراء التجريبي

A solution of 2.26 g of p-toluenesulfonic acid chloride in 5 ml of pyridine was gradually added dropwise to a cooled solution of 2.04 g of 6-pentyloxyheptanol in 8 ml of pyridine for 7 min. below 5° C. After stirring for 5 hours at room temperature, the reaction mixture was injected into 150 ml of cold water and, after being acidified to pH 3 with 6N-hydrochloric acid, was extracted with ethyl acetate. The resultant solution was washed with water and dried with anhydrous magnesium sulfate, followed by distilling-off of the solvent to obtain 2.98 g of (6-pentyloxyheptyl)-p-toluenesulfonate.
