Takahashi, Shiro et al. published their research in Chemical & Pharmaceutical Bulletin in 1970 | CAS: 1843-21-6

N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazoles in peptides or their ability to bind proteins, DNA and RNA has led to many synthetic studies and new applications. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 °C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.Name: N-Phenylbenzo[d]thiazol-2-amine

Heteroaromatic N-oxide. X. Synthesis and reactions of benzothiazole 3-oxide was written by Takahashi, Shiro;Hashimoto, Shinichiro;Kano, Hideo. And the article was included in Chemical & Pharmaceutical Bulletin in 1970.Name: N-Phenylbenzo[d]thiazol-2-amine This article mentions the following:

Benzothiazole 3-oxide (I) was synthesized from its 2-Me derivative, via the corresponding aldoxime, carbonitrile, imido ester and carboxylic acid. The reactions of I: deoxygenation, reactions with various nucleophilic agents (tosyl chloride, Ac2O, PhMgBr, NaHSO3, N2H4.H2O and KCN-BzCl) involving some 1,3-dipolarophiles (benzyne, PhNCO and tetracyanoethylene), and quaternizations were investigated and compared with those of the corresponding imidazole N-oxide. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Name: N-Phenylbenzo[d]thiazol-2-amine).
