実験手順
3.00 g (17.75 mmol) of 1,3-dimethyl-2,2-dichloroimidazolidine and 2.38 g (17.75 mmol) of sodium methylsulfate are mixed with 20 ml of dry acetonitrile. The reaction mixture is stirred for 5 hours at room temperature, and the precipitate NaCl is filtered off. The solvent is distilled off, and the residue is dried for 1 hour under a reduced pressure of 7 Pa and at 50° C., giving 4.09 g of 1,3-dimethyl-2-chloroimidazolidinium methylsulfate as a viscous material, corresponding to a yield of 94.2%.
