  喹诺酮羧酸衍生物或二氮杂萘酮羧酸衍生物的制备方法

  摘要：

  本发明属于医药化工领域，涉及喹诺酮羧酸衍生物或二氮杂萘酮羧酸衍生物的制备方法，具体涉及7‑取代‑3‑喹诺酮羧酸衍生物或7‑取代‑1,5‑二氮杂萘酮羧酸衍生物的制备方法。所述的制备方法包括如下步骤：(1)在有机溶剂中，将硼螯合物II与有机胺III在有机硅化合物下发生偶联反应，得到化合物IV；(2)将化合物IV与盐酸混合，随后过滤分离沉淀的化合物I。本发明所述制备方法相比于传统方法，它条件更为温和，能够减少底物喹啉羧酸硼酸酯的水解，同时避免了副产物HF对产品纯度的影响，收率高，纯度高，使用有机硅相比于传统的碱，更适合用于7‑取代‑3‑喹诺酮羧酸衍生物或7‑取代‑1,5‑二氮杂萘酮羧酸衍生物的工业制备。
