During the process development of the product 6 via the route presented in Scheme 1, we encountered several safety issues that had to be resolved before moving these stages to production. In each case, the safety issues are related to the interaction of the solvent used, DMSO (dimethylsulphoxide, 3), with one of the other chemicals. Also in this case (Bollyn, M. Org. Process Res. Dev. 2005, 9, 982−996)
在通过方案1提出的路线开发产品6的过程中,我们遇到了几个安全问题,在将这些阶段移至生产之前必须解决。在每种情况下,安全性问题都与所用溶剂DMSO(二甲亚砜3)与其他一种化学药品的相互作用有关。此外,在这种情况下(Bollyn,M.有机化学工艺水库开发。 2005,9,982-996),我们应用了失控指数为指导,以决定是否一个过程可以在生产规模下运行。反应量热法在RC1(组合梅特勒-托利多- [R反应的影响Ç alorimeter 1; http://www.RXEForum.com),并在ARC热分析(甲ccelerating ř吃Ç alorimeter; http://www.thermalhazardtechnology.com)组合使用与工艺参数研究设计过程阶段被认为是安全的(足够),用于生产规模。
