Electric Literature of 13275-42-8, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 13275-42-8 as follows.

General procedure: An oven-dried Schlenk tube equipped with a Teflon valve was charged with a magnetic stir bar, CuCl2 (7 mg, 0.05 mmol, 10 mol%), K3PO4 (212 mg, 1 mmol), 1,10-phenanthroline monohydrate (20 mg, 0.1 mmol, 20 mol%), 2-(2-bromophenyl)-1,4,5,6-tetrahydropyrimidine 1 or 2-(2-bromophenyl)- 1H-benzo[d]imidazole 4 (0.5 mmol), and N-heterocycle 2 (0.5 mmol). The Schlenk tube was evacuated and backfilled with O2 (this procedure was repeated three times). Under a counter flow of O2, DMF (2.0 mL) was added using a syringe. The reaction mixture was stirred at 110 C for 24 h. After the reaction was completed, the mixture was extracted with dichloromethane (3 ¡Á 15 mL), and then the organic layer was washed with brine (3 ¡Á 10 mL) and dried over anhydrous Na2SO4. Subsequently, the solvent was removed, and the product was purified by column chromatography on silica gel using a mixture of dichloromethane and methanol as the eluent, affording the pure products.

According to the analysis of related databases, 13275-42-8, the application of this compound in the production field has become more and more popular.

Adding a certain compound to certain chemical reactions, such as: 13275-42-8, name is 2-(2-Bromophenyl)-1H-benzo[d]imidazole, belongs to imidazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 13275-42-8, category: imidazoles-derivatives

General procedure: Equimolar quantity of 2-(2-bromophenyl)-1H-benzo[d] imidazole (2) and aniline derivatives in 45 ml of 1,4-dioxan was refluxed for 14 hr with continuous stirring at 80. The completion of reaction was checked by TLC. The reaction mixture was kept overnight in a refrigerator. The solvent was evaporated and a gummy solid mass was obtained. The gummy solid was then washed with cold water and recrystallized from ethanol and water (4:6) to obtain the compounds (3a-3h).
