Adding a certain compound to certain chemical reactions, such as: 934-32-7, name is 1H-Benzo[d]imidazol-2-amine, 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 934-32-7, Product Details of 934-32-7
General procedure: A mixture of -Fe2O3starch-n-butyl SO3H (10 mg),aromatic aldehyde (1.0 mmol), dimedone (1.0 mmol),2-aminobenzimidazole (1.0 mmol) was heated in an oilbath (100 C) for the appropriate reaction time until thecompletion. The progress of the reaction was monitoredby TLC (n-hexane:ethyl acetate, 8:4). After completion ofthe reaction water (10 mL) was added and the catalyst wassegregated using an external magnet, washed with chloroform,dried out, and used directly without an appreciableloss of its activity for the next run. The product was purifiedby recrystallization from EtOH and dried in air.
