Procedure

20.8 g (0.20 mol) of 2-ethoxypropanol are added slowly during 20 minutes with stirring to a mixture of 43.3 g (0.227 mol) of toluene-p-sulphonylchloride and 20 ml of dry pyridine. The temperature of the reaction mixture is kept at 20° with external cooling. After stirring for 2 hours at 20°, the mixture is poured into ice-water and extracted with ether. The ether layer is washed with 2N sulphuric acid, with water and with saturated sodium hydrogencarbonate solution. After drying over sodium sulphate, filtration and evaporation in vacuo, 2-ethoxypropyl toluene-p-sulphonate is obtained as a yellow oil.
