Electric Literature of 4857-06-1, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 4857-06-1, name is 2-Chloro-1H-benzo[d]imidazole, This compound has unique chemical properties. The synthetic route is as follows.
Sodium hydride (purity 55%)(516 mg, 12.0 mmol) was added to a N,N-dimethylformamide solution (8.0 ml) of 2-chloro-1H-benzimidazole (1.52 g, 10.0 mmol), at 0C, under nitrogen stream, and stirring was carried out for 20 minutes. Methyl iodide (0.750 ml, 12.0 mmol) was further added, and stirring was carried out under room temperature for 2 hours. Water was added to the reaction solution, and the resulting solid substance was collected by filtration to afford 2-chloro-1-methyl-1H-benzimidazole (1.51 g, yield 91%) as a white solid.
The chemical industry reduces the impact on the environment during synthesis 2-Chloro-1H-benzo[d]imidazole. I believe this compound will play a more active role in future production and life.
