Procedure

3.0 g of diethylmethylamine was dissolved in 30 cm3 of 2-butanone, to which was then gradually added 5.7 g of p-toluenesulfonic acid monohydrate while stirring. The stirring was continued for an additional one hour, and the solvent was then distilled off in vacuo. The obtained solid was recrystallized from acetone to obtain a diethylmethylamine salt of p-toluenesulfonic acid.
