  开发 KRAS G12C 抑制剂 Divarasib 中高取代喹唑啉核心的简化制造工艺

  摘要：

  本文介绍了一种合成高功能化喹唑啉的简化工艺，该工艺能够实现 KRAS G12C 抑制剂divarasib的后期制备。该合成的亮点是关键的 2-氨基-4-溴-3-氟苯甲腈中间体的四步叠层制备、使用 NCS 和催化 HCl 的关键芳族氯化、使用 CO 2和 DBU 环化为喹唑啉二酮、以及 DABCO−MsOH 催化的 Halex 反应，形成目标氟化喹唑啉2。在氯化步骤中，我们遇到了不寻常的卤素扰乱，导致产生了关键的 4,5-二氯和 4,5-二溴杂质，由于下游化学中的净化能力极小，需要将这些杂质控制在较低水平。通过九个化学步骤和五次分离，以 39% 的总产率和 99.5 面积% HPLC 纯度制备 >500 kg 的喹唑啉2，证明了制造过程。

  The present invention provides novel tricyclic 1,4-benzodiazepinone derivatives of the general formula (I) and pharmaceutical compositions containing them. Moreover, the compounds of formula (I) and the pharmaceutical compositions containing them are provided for use in the treatment and/or prophylaxis of conditions associated with altered glutamatergic signalling and/or functions, and/or conditions which can be affected by alteration of glutamate level or signalling in mammals. The tricyclic 1,4-benzodiazepinone derivatives of formula (I) can act as modulators of nervous system receptors sensitive to glutamate, in particular as modulators of metabotropic glutamate receptors (mGluRs), which makes them particularly suitable for the treatment and/or prophylaxis of acute and chronic neurological and/or psychiatric disorders. The present invention further provides tricyclic 1,4-benzodiazepinone derivatives of formula (I) that are modulators of metabotropic glutamate receptors (mGluRs), particularly positive allosteric modulators of mGluRs, and more specifically positive allosteric modulators of mGluR3.
