Commercial Manufacturing of Propofol: Simplifying the Isolation Process and Control on Related Substances
A commercially
viable manufacturing process for propofol (<b>1</b>) is described.
The process avoids acid–base neutralization
events during isolation of intermediate, 2,6-di-isopropylbenzoic acid
(<b>3</b>) and crude propofol, and thus simplifies the synthesis
on industrial scale to a considerable extent. Syntheses of five impurities/related
substances (USP and EP) are also described
