Procedure

A mixture of 1.76 g of tetrahydrothiophene and 3.72 g of methyl p-toluenesulfonate was allowed to stand for 3 days at room temperature. The crystals which were deposited were collected by filtration, washed with diethyl ether, and dried. By this procedure crystals of S-methyltetrahydrothiophenium p-toluenesulfonate were obtained. After the product was recrystallized, it had a melting point of 145.0° to 148.0°C.
