Related Products of 4857-06-1,Some common heterocyclic compound, 4857-06-1, name is 2-Chloro-1H-benzo[d]imidazole, molecular formula is C7H5ClN2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Commercially available 2-chloro-1H-benzo[d]imidazole (250 mg, 1.64 mmol) was dissolved in DMF (4.7 mL), dimethylamine (50% aqueous solution, 0.50 mL, 4.92 mmol) was added, and the mixture was stirred with heating at 200C for 30 min in an Emrys Optimizer microwave synthesizer. Water was added to the mixture, and the precipitated crystals were collected by suction filtration to give N,N-dimethyl-1H-benzo[d]imidazole-2-amine (234 mg, 89%). ESIMS m/z: 162 (M + H)+; 1H NMR (270 MHz, DMSO-d6, delta): 3.03 (s, 6H), 6.79-6.97 (m, 2H), 7.07-7.20 (m, 2H), 11.17 (br s, 1H)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Chloro-1H-benzo[d]imidazole, its application will become more common.
