In 2019,Letters in Organic Chemistry included an article by Nematpour, Manijeh; Abedi, Elham; Abedi, Elahe. HPLC of Formula: 934-32-7. The article was titled 《A Novel One-pot Protocol for the Cu-Catalyzed Synthesis of Nine 2-Aminobenzimidazole Derivatives from o-Phenylenediamine and Trichloroacetonitrile》. The information in the text is summarized as follows:
The synthesis of a variety of 2-aminobenzimidazoles I (R = H, Me, OMe, Cl, Br; R1 = H, Me, Cl; X = Y = CH, N) via one-pot reaction of o-phenylenediamine and trichloroacetonitrile catalyzed by copper (II) acetate in THF at room temperature, with good yields is described. Use of simple and readily available starting materials, good to high yields, free ligand, and ease of purification procedure are important features of this protocol. After reading the article, we found that the author used 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7HPLC of Formula: 934-32-7)
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.HPLC of Formula: 934-32-7
