Procedure

A 20.0 g quantity of N-methoxymethyl-N-methylpyrrolidinium chloride prepared in Example 10 was dissolved in 120 g of water, and 22.2 g of potassium hexafluorophosphate was added to the solution, whereupon a white solid separated out. The mixture was stirred for 30 minutes, and dichloromethane was thereafter added to the mixture for extraction. The organic layer was washed with 120 g of water six times and then dried, affording 25.1 g of a white solid as the desired product.
