N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current.Various laboratory methods exist for the organic synthesis of thiazoles. For example, 2,4-dimethylthiazole is synthesized from thioacetamide and chloroacetone.Recommanded Product: 1843-21-6

Ligand free copper-catalyzed N-arylation of heteroarylamines was written by Wang, Deping;Kuang, Daizhi;Zhang, Fuxing;Liu, Yang;Ning, Shunhua. And the article was included in Tetrahedron Letters in 2014.Recommanded Product: 1843-21-6 This article mentions the following:

An efficient protocol for the ligand-free Cu-catalyzed N-arylation of heteroarylamines was developed. With the use of 1% CuI, a wide range of aryl iodides and bromides coupled with heteroarylamines affording the corresponding products in high yields. Furthermore, this protocol was particularly suitable for reactions of hindered aryl iodides with 2-aminopyridines. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Recommanded Product: 1843-21-6).
