Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. Like 2386-57-4, Name is Sodium methanesulfonate. In a document, author is Gu, Jianhui, introducing its new discovery. Synthetic Route of 2386-57-4.
Umeclidinium bromide, a drug used for chronic obstructive pulmonary disease, is synthesized through a new intermediate of phenyl(quinuclidin-4-yl)methanone. This novel method with simple operation flow and cheap reagents, makes it suitable for scale up. The overall four-step process provides umeclidinium bromide in 29% yield and the purity up to 99.83%. The X-ray crystal structure of the drug molecule was first reported.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 2386-57-4 Synthetic Route of 2386-57-4.
