(1) was developed. This alternative approach circumvented the purification of intermediates by column chromatography and provided access to multikilogram quantities of the key intermediate, 6. The safety aspects of the synthetic approach to the other fragment of the API (TosMIC 10) were critically evaluated, and a robust process for its large-scale synthesis was successfully demonstrated.
开发了可扩展的小分子TGFβR1
抑制剂BMS-986260(1)的途径。这种替代方法避免了通过柱色谱法纯化中间体的问题,并提供了获取多千克量的关键中间体6的途径。对A
PI的其他片段(TosMIC 10)的合成方法的安全性进行了严格评估,并成功证明了其大规模合成的可靠过程。
