24.8 g (0.2 mole) of thioanisole was heated to 90° C. with stirring and 27.8 g (0.22 mole) of dimethyl sulfate was added dropwise thereto over a period of 30 minutes keeping the temperature between 90 ° and 95° C. After the stirring was continued for an additional 30 minutes at the same temperature, the reaction mixture was cooled to room temperature to give phenyldimethylsulfonium methylsulfate quantitatively as solid mass.
