The C2 amination of imidazo[4,5-b]pyridines was accomplished through C2 halogenation followed by substitution (SNAr) with functionalized primary and secondary amines. This regioselective sequence is operationally simple and provides an easy access to derivatives of protected imidazo[4,5-b]pyridines.
咪唑并[4,5-b]吡啶的 C2 amination 是通过 C2 卤化,然后用官能化的伯胺和仲胺进行取代 (SNAr) 来完成的。这种区域选择性序列操作简单,易于获得受保护的咪唑并[4,5-b]吡啶衍生物。
