LONG Jie; etc(Hunan Research Institute of Chemical Industry; Changsha Hunan 410007; China) |
Abstract:Amino 4 chloro benzothiazole was prepared from 2 chloro phenyl thiourea and sulfuryl chloride by cyclization in 94.8% yield. The effect of the kinds of solution medias, the proportion of materials, the reaction temperature, and the time on the yield was investigated. The process of synthesis was improved. |
Key words:benzothiazole; synthesis |
