Synthesis
editMesitol is the main product from the methylation of phenol with methanol in the presence of a solid acid.[2]
It can also be obtained by reaction of mesitylene with peroxymonophosphoric acid:[3]
An alternative route involves palladium-catalyzed reaction of bromomesitylene with potassium hydroxide.[4]
