Reaction of 4,5-dichloro-3-trichloromethylisothiazole with heterocyclic amines
摘要:
4,5-Dichloro-3-trichloromethylisothizole reacted with piperidine, morpholine, pyrrolidine, and piperazine in DMF to give 81-96% of the corresponding 5-amino-4-chloro-3-trichloromethylisothiazoles as a result of selective nucleophilic replacement of the 5-chlorine atom. Acylation of 4-chloro-5-(piperazin-1-yl)-3-trichloromethylsothiazole with acetyl chloride gave 4-cliloro-5-(4-acetylpiperazin-1-yl)-3-trichloromethylisothiazole.
