Procedure

By following the same procedure (2nd step) of Example 1 except that 10.0 g of N,N-dimethylpyrrolidinium methyl carbonate thus obtained and 12.9 g of an aqueous solution of 42% HBF4 were used, 10.1 g (yield of 92.4% to N-methylpyrrolidine) of high-pure dimthylpyrrolidinium tetrafluoroborate was obtained.
