(Mountain_Girl: "P-MeO Phenol abstracts 1980-1999 #1", Methods Discourse) you can find a reference toPatent DE3145212 (http://l2.espacenet.com/dips/viewer?PN=DE3145212&CY=gb&LG=en&DB=EPD)
akaPatent US4469897 (http://l2.espacenet.com/dips/viewer?PN=US4469897&CY=gb&LG=en&DB=EPD)
which details producing p-methoxyphenol from hydroquinone using MeOH, catalytic CuCl2 and O2 or air. Most of the examples are run under pressure but there is one example that shows it can be done under reflux. I assume this method would be a bit cleaner but have no empirical evidence. I'm sure many bees here would appreciate such information.Post 474331 (https://www.thevespiary.org/talk/index.php?topic=12548.msg47433100#msg47433100)

(Antoncho: "Methylation of hydroquinone w/NaMeSO4: good news!", Novel Discourse) possible with the 2-HO-5-MeO-Salicylaldehyde? Be nice this way as storage/prep of the salt seems safer and simpler.
