Prasoona, G.; Kishore, B.; Brahmeshwari, G. published their research in Russian Journal of Organic Chemistry in 2021. The article was titled 《A Simple and Efficient Four-Component One-Pot Synthesis of Novel 2-Aryl-3-benzimidazolyl-3,4-dihydroimidazo[4,5-b]indoles Catalyzed by Ceric Ammonium Nitrate in Aqueous Ethanol》.Reference of 1H-Benzo[d]imidazol-2-amine The article contains the following contents:
A simple and efficient protocol for the synthesis of benzimidazolylimidazo[4,5-b]indoles was developed through the condensation of 2-aminobenzimidazoles, aromatic aldehydes, ammonium acetate and isatins via multicomponent reaction strategy using ceric ammonium nitrate as catalyst. The key advantages of the four-component reaction were easy work-up, high yield, short reaction time and environmentally safe solvent. After reading the article, we found that the author used 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Reference of 1H-Benzo[d]imidazol-2-amine)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Reference of 1H-Benzo[d]imidazol-2-amine
