In an article, published in an article, once mentioned the application of 105827-91-6, Name is 2-Chloro-5-(chloromethyl)thiazole,molecular formula is C4H3Cl2NS, is a conventional compound. this article was the specific content is as follows.name: 2-Chloro-5-(chloromethyl)thiazole
This invention relates to methods for substitution of an amino group of a heterocyclic primary amine by a chlorine atom and synthesis of 2-chloro-5-methylthiazole and its derivatives by application thereof. Typically, a heterocyclic primary amine and sodium nitrite are caused to react in the presence of hydrochloric acid, followed by heating the formed diazonium base at 30-100 C. in the presence of an equimolar or more of hydrochloric acid to substitute the amino group by the chlorine atom. Further, 2-amino-5-methylthiazole and sodium nitrite are caused to react in the presence of hydrochloric acid, followed by heating the formed diazonium base at 30-100 C. in the presence of an equimolar or over of hydrochloric acid to give 2-chloro-5-methylthiazole. Then, the resultant 2-chloro-5-methylthiazole is caused to react with a chlorinating agent to give 2-chloro-5-chloro-methylthiazole.
