Some scientific research about 6-Aminobenzimidazole

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

Application of 934-22-5, A common heterocyclic compound, 934-22-5, name is 6-Aminobenzimidazole, molecular formula is C7H7N3, its 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.

General procedure: A dry 50 mL flask was charged with 2-halogenated aromatic aldehyde 1 (1.0 mmol), 1H-benzo[d]imidazol-5-amine (0.133 g,1.0 mmol), cyclohexane-1,3-diones (1.0 mmol), CuI (10 mg), L-proline(6 mg), Cs2CO3 (650 mg) and dioxane (10 mL). The reaction mixture was stirred at reflux for 10-18 h. After completion of the reaction, as indicated by TLC, the solid was filtered off by a fast and hot filtration, and the products of 4 were obtained as pale yellow powder or crystals, when the mixture was allowed to cool down to room temperature.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
