Herein, we report the kilogram-scale synthesis of CH4930808 (1), a novel anti-hepatitis C virus agent. While pursuing improved productivity using many through-process strategies, we conducted scrupulous impurity control. Finally, we successfully developed a practical and scalable process for the synthesis of (1·1.5Na·2.5H2O), by which we prepared 3.28 kg of the active pharmaceutical ingredient for
在此,我们报道了新型抗丙型肝炎病毒药物CH4930808(1)的千克级合成。在使用许多贯穿过程的策略追求提高生产率的同时,我们进行了严格的杂质控制。最后,我们成功开发了一种实用且可扩展的合成(1 ·1.5Na·2.5H 2 O)的方法,由此制备了3.28千克的活性药物成分用于临床研究。
