Procedure

A 30.0 g quantity of N-methoxymethyl-N-methylpyrrolidinium chloride prepared in Example 10 was dissolved in 30.0 g of MeOH, and 80.0 g of methanol solution of 35 wt. % trifluoromethanesulfonic acid was added to the solution. The mixture was heated at 130° C. in a nitrogen stream to remove hydrogen chloride produced as a by-product, an excess of trifluoromethanesulfonic acid and methanol, giving 49.0 g of the desired product.
