Kallur, H. J.;Mathapati, Prabhudev S.;C., Kishore Singh;Malpani, Ashok published 《Synthesis, characterization and anthelmintic screening of some new benzothiophene derivatives》 in 2020. The article was appeared in 《World Journal of Pharmaceutical Research》. They have made some progress in their research.Recommanded Product: 6285-57-0 The article mentions the following:
The proposed work was carried out by following Schemes. In the Scheme-I the starting material cinnamic acid was reacted with thionyl chloride, in presence of pyridine in chlorobenzene medium to yield 3- chlorobenzo[b]thiophene-2-carbonylchloride. Where as in the Scheme-II the 2-amino-6-substituted benzothiazoles I (R = Me, COOEt, Cl, OMe, F, nitro) was prepared by the reaction of 4-substituted anilines 4-RC6H4NH2 and potassium thiocyanate in presence of bromine in acetic acid. In the scheme-III, the compound N-(6-substituted-1,3-benzothiazol-2-yl)-3-chloro-1-benzothiophene-2-carboxamides II was prepared by reacting 3-chlorobenzo[b]thiophene-2-carbonylchloride and 2-amino-6-substituted benzothiazoles I in pyridine medium refluxed for 10-15 h. The synthesized compounds II were evaluated for the anthelmintic activity. And 6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) was used in the research process.
6-Nitrobenzo[d]thiazol-2-amine(cas:6285-57-0 Recommanded Product: 6285-57-0) inhibits the activity of amines, which are small molecules found in many pharmaceuticals. The chemical structure of this drug contains one or more methylene groups that can be activated by diazonium salt to form an intermediate molecule with a reactive amine group.
