Synthesis

edit

Mesitol 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]
