Procedure
Methyl allylsulfonate (21.4 g, 0.157 mol) synthesized by the conventional method and pyridine (13.1 g, 0.166mol, 1.05 eq) were reacted by stirring for 2 hours at 80° C. After completed the reaction, unreacted pyridine was removed under reduced pressure, crude substance was washed with ethyl acetate several times. The desired product of 1-methylpyridinium allylsulfonate (31.4 g, 0.146 mmol, 93% yield) was obtained by drying by heating under reduced pressure. Melting point was 39° C. Measurement result of 1H NMR was shown as follows:
