10 ml of dry chloroform and 1.29 g (11.00 mmol) of N,N-dimethyltrimethylsilylamine are added to 2.45 g (9.93 mmol) of bis(dimethylamino)chlorocarbenium methylsulfate. The reaction mixture is stirred for 1 hour at room temperature, and all volatile compounds are subsequently removed under reduced pressure. The residue is dried for a further 1 hour under reduced pressure at 7.0 Pa and an oil-bath temperature of 50° C., giving 2.42 g of hexamethylguanidinium methylsulfate, corresponding to a yield of 95.5%.
