Reaction Conditions

Reaction Steps

Dimethyl sulfide (25.0 mL) is cooled to 0° C., and dimethyl sulfate (25.0 mL) is added. The liquid is stirred at 0° C. and allowed to warm slowly as the ice in the cooling bath melts. The following day, ether is added and the solid mass crushed with a stirring rod. The solid is filtered, washed well with ether, and dried in vacuo to provide 48.0 g of the salt as a white crystalline solid.
