Lithium N-methylmethanaminide → 1,3-Dimethyl-2-dimethylaminoimidazolidinium nitrate

Participants

Reaction Steps

3.00 g (15.34 mmol) of 1,3-dimethyl-2-chloroimidazolidinium nitrate and 0.78 g (15.29 mmol) of lithium dimethylamide are dissolved in 20 ml of acetonitrile under a protective-gas atmosphere (argon). The reaction mixture is stirred for 5 hours at room temperature, and LiCl is subsequently filtered off. The salt LiCl is washed with 5 ml of acetonitrile, and the organic phases are combined. The solvent is distilled off, and the residue is dried under reduced pressure at 7 Pa and 50° C., giving 2.91 g of 1,3-dimethyl-2-dimethylaminoimidazolidinium nitrate as a liquid, corresponding to a yield of 92.2%.
