2-Bromo-N-(p-toluenesulfonyl)pyrrole (2), a crystalline stable derivative of 2-bromopyrrole (1) has been prepared in 80% yield by bromination of pyrrole, followed by conversion to the N-(p-toluenesulfonyl) derivative. This compound is stable indefinitely at ambient temperature. Compound 2 is an excellent substrate for Suzuki coupling with arylboronic acids.
2-溴-N-(对甲苯磺酰基)吡咯 (2) 是2-溴吡咯 (1) 的一种晶体稳定衍生物,通过对吡咯进行溴化,然后转化为N-(对甲苯磺酰基)衍生物,得到了80%的产率。该化合物在常温下可以无限期稳定。化合物2是与芳基硼酸进行铃木偶联反应的优秀底物。
