3-Bromomethyl-7-chlorobenzo[b]thiophen has been converted into related amino-, guanidino-, and ureido-compounds, among others, by modifications of known methods. Nitration, bromination, and acetylation of 7-chloro-3-methylbenzo[b]thiophen gave mainly the 2-substituted compounds. 7-Hydroxy- and 7-mercapto-3-methylbenzo[b]thiophen resulted from the treatment of the Grignard reagent derived from 7-ch
通过已知方法的改进,3-溴甲基-7-氯苯并[ b ]噻吩已被转化为相关的氨基,胍基和脲基化合物。7-氯-3-甲基苯并[ b ]噻吩的硝化,溴化和乙酰化反应主要产生2-取代的化合物。7-羟基和7-巯基-3-甲基苯并[ b ]噻吩起因于格利雅的治疗试剂,从7-氯-3-甲基苯并〔b〕噻吩衍生的与氧或硫。7-氯基团的直接亲核取代也以高收率得到7-羟基-或7-氨基-3-甲基苯并[ b ]噻吩。
