2.01 g (11.7 mmol) of sodium trifluoromethanesulfonate in 20 ml of acetonitrile are added with stirring at room temperature to a solution of 2.0 g (11.7 mmol) of bis(dimethylamino)dichloromethane in 20 ml of acetonitrile. The mixture is stirred for one hour, and 40 ml of diethyl ether are added. After stirring for 12 hours, the solid NaCl is subsequently filtered off. The solvent is distilled off, and the crystals formed are dried under a reduced pressure of 10.0 Pa, giving 3.29 g of bis(dimethylamino)chlorocarbenium trifluoromethanesulfonate, corresponding to a yield of 98.8%.
