专利号:US-5811555-A 优先权日:1995-11-22 标题:Method for substitution of an amino group of a primary amine by a chlorine atom and a synthetic method by application thereof 发明人:WAKASUGI TAKASHI; MIYAKAWA TADASHI; TANONAKA TAKAYUKI 权利人:KUREHA CHEMICAL IND CO LTD 摘要: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. n 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.
