Yamashita, Tomohiro et al. published their research in Synthetic Communications in 2009 | CAS: 13060-24-7

2-Octylbenzimidazole (cas: 13060-24-7) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Synthetic Route of C15H22N2

New Procedure for the Synthesis of 2-Alkylbenzimidazoles was written by Yamashita, Tomohiro;Yamada, Shozo;Yamazaki, Yasundo;Tanaka, Hideo. And the article was included in Synthetic Communications in 2009.Synthetic Route of C15H22N2 This article mentions the following:

Simple, economical, and environmentally friendly method to synthesize 2-alkylbenzimidazoles, e.g., I (Et, n-octyl, c-hexyl), was developed by modifying the conventional method between o-phenylenediamine and aldehydes. In the experiment, the researchers used many compounds, for example, 2-Octylbenzimidazole (cas: 13060-24-7Synthetic Route of C15H22N2).
