Reaction Steps

Para-toluenesulphonyl chloride (20.5 g) was added to a mixture of 2-chloroethanol (8.6 g) and pyridine (50 ml). After stirring for one hour at 0° C., the mixture was added to ice and the organic phase was extracted with ether. The extract was washed with dilute hydrochloric acid, dried with magnesium sulphate, and evaporated, to yield 2-chloroethyl-p-toluenesulphonate.
