실험 절차

2.34 g (24.1 mmol) of a 65% nitric acid are added with vigorous stirring to 3.77 g (22.3 mmol) of 2,2-dichloro-1,3-dimethylimidazolidine. This reaction mixture is evacuated firstly at room temperature for one hour at 4 kPa and for 20 min at 7 Pa. After cooling using an ice bath, the mixture is evacuated again for 6 hours at 7 Pa, giving 3.7 g of 1,3-dimethyl-2-chloroimidazolidinium nitrate as an oil, corresponding to a yield of 85.1%.
