Methyl p-toluenesulfonate → 1,1-Dimethyl-2-hydroxymethylpyrrolidinium p-toluenesulfonate

Participants

Reaction Steps

In 10 ml of acetone was dissolved 1.47 g of 1-methyl-2-pyrrolidinemethanol, and 2.38 g of methyl p-toluenesulfonate was added dropwise to the resulting solution. The mixture was stirred at room temperature, heated under reflux, and cooled to precipitate crystals. The crystals were collected by filtration and dried to give 2.67 g of the desired compound.
