multikilogram production of BIIB068 hemiadipate are discussed. Process optimization resulted in (1) removal of transition metal from the process, (2) a streamlined process with significantly improved overall yield, and (3) appropriate impurity control (including potential mutagenic impurities), which enabled delivery of quality material for toxicology studies and clinical trials.
讨论了导致多千克生产BIIB068半
己二酸酯的
化学工艺开发工作。工艺的优化导致(1)从工艺中去除过渡
金属;(2)精简的工艺具有显着提高的总收率;(3)适当的杂质控制(包括潜在的诱变杂质),从而可以提供用于毒理学研究的优质材料和临床试验。
