Procedure

To a 300 ml four necked flask, 13.78 g (0.101 mol) of 2,2-difluoro-1,3-dimethylimidazolidine (DFI), 10.25 g (0.0995 mol) of sodium bromide, and 126.5 g of acetonitrile were charged and reacted at 25° C. for 4 hours in a nitrogen atmosphere. The yield of 2-fluoro-1,3-dimethylimidazolinium=bromide was 99%.
