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.
提供了一种新颖的工艺,用于高效制备结构式I的不对称化合物,包括铜催化的碳氮交叉偶联步骤。本发明所描述的工艺可用于制造聚(ADP核糖)聚合酶(PARP)抑制剂,这些抑制剂可能对癌症的治疗有用。特别地,本发明描述了一种制造PARP抑制剂2-4-[(3S)-哌啶-3-基]苯基}-2H-吲唑-7-羧酰胺的工艺。
