discovery program, 4-pyrazin-2-yl-1H-pyrrole-2-carboxamides were accessed along with a number of bicyclic analogues. Routes to these compounds were largely absent from the scientific literature. The synthesis of a 4-(pyrazin-2-yl)-1H-pyrrole-2-carboxamide and several fused bicyclic analogues all using standard procedures (SNAr, borylation, C–C cross couplings, hydrolysis, amide bond formation, cyclisation
作为药物发现计划的一部分,4-pyrrazin-2-yl-1 H -pyrrole-2-carboxamides 与许多双环类似物一起被使用。科学文献中基本上没有找到这些化合物的途径。4-(pyrazin-2-yl)-1 H -pyrrole-2-carboxamide 和几种稠合双环类似物的合成均使用标准程序(S N Ar、
硼化、C-C 交叉偶联、
水解、酰胺键形成、环化,卤化和烷基化)从容易获得的起始材料报道。每个最终化合物的合成序列范围为 4-12 步,分离中间体的产率范围为 20% 至 ∼100%。
