A novel process is provided for the efficient preparation of an asymmetric compound of structural formula I:
comprising a copper-catalyzed, carbon-nitrogen cross-coupling step. The process described as part of the present invention can be used to manufacture poly (ADP-ribose) polymerase (PARP) inhibitors, which may be useful for the treatment of cancer. In particular, the present invention describes a process for the manufacture of the PARP inhibitor, 2-4-[(3S)-piperidin-3-yl]phenyl}-2H-indazole-7-carboxamide.
本发明提供了一种高效制备结构式I的不对称化合物的新工艺,其中包括铜催化的碳氮交叉偶联步骤。所述的工艺可以用于制造聚(ADP-核糖)聚合酶(PARP)抑制剂,这些抑制剂可能有助于癌症的治疗。具体而言,本发明描述了一种用于制造PARP抑制剂2-4-[(3S)-哌啶-3-基]苯基}-2H-吲唑-7-甲酰胺的工艺。
