Procedure

In 50.0 g of water was dissolved 25.1 g of N-methoxymethyl-N-methylpyrrolidinium chloride and thereto was added 30.0 g of lithium hexafluoroarsenate (reagent, Aldrich Corp.). The mixture was reacted at room temperature for 1 hour, and 79.2 g of dichloromethane was added to the mixture for extraction. The extract was washed with 100 ml of water 15 times, thereafter concentrated and dried in a vacuum, giving 32.4 g of the desired product in the form of a white solid.
