Synthesis of 7-Substituted Derivatives of 5,8-Dimethylisoquinoline
摘要:
7-Bromo-5,8-dimethylisoquinoline was selectively synthesized by the bromination of 5,8-dimethylisoquinoline obtained in five steps from p-xylene as a starting material. Further, 7-bromo-5,8-dimethylisoquinoline gave 7-amino-5,8-dimethylisoquinoline by the reaction with ammonia and various 7-anilino-5,8-dimethylisoquinolines via a palladium-catalyzed coupling reaction with anilines.
