2-Chloro-1,3-dimethylimidazolidinium chloride Use and Manufacturing
For 1000 ml three port in the reaction bottle, by adding 1, 3-dimethyl-2-imidazolidinone (34.2 g, 0.3 mol), carbon tetrachloride (400 ml), stirring slowly dropwise solid phosgene carbon tetrachloride solution (containing solid phosgene 30 g, 0.1 mole, carbon tetrachloride 100 ml), the reaction mixture is kept below 5 °C, violent mixing 0.5 hours, the reaction at room temperature 1 hour, heating to 50 °C, maintain 4 hours. To be the reaction product is cooled to room temperature, filter, a small amount of carbon tetrachloride washing, get a pure white crystalline product chloropivaloyl 1, 3-dimethyl-2-chlorotrifluoromethylbenzene imidazoline 49 g, yield of 96.6percent, Under an inert atmosphere, 1, 3-Dimethyl-2-imidazolidinone (7.0 mL, 64 mmol) was dissolved in anhydrous benzene (25 mL). To this oxalyl chloride (7.2 mL, 80 mmol) was added, and the solution was refluxed for 5 hours, and allowed to sit at room temperature overnight. The solution was filtered quickly to give 2-chloro-1, 3-dimethylimidazolinium chloride (7.5815 g, 44.85 mmol) in 70.1percent yield.1, 3-dimethyl-2-imidazolidinone 3.50g (30.7 mmol), and the mixture was heated for 5 hours and stirred at 140 of chloride phthalic acid 6.54g (32.4 mmol). After cooling, the crystal upon addition of 1, 4-dioxane 25mL precipitated, filtered with a glass filter, washed twice with 1, 4-dioxane 10 mL, washed once with ether 5 mL, and dried under vacuum. To give 2-chloro-1, 3-dimethyl imidazolium chloride 2.72g (53percent yield).
Used in the one-pot synthesis of 2-aminobenzimidazoles.
