Participants

Reaction Steps

Dimethyl sulfate (39 ml; 0.41 mol) was added to a solution of orcinol (64 g; 0.45 mol) in 10% aqueous sodium hydroxide solution (360 ml). The mixture was refluxed for 1½ hours and extracted with ether. The organic phase was evaporated and purified by flash chromatography eluting with dichloromethane/ethanol (98/2) to give 3-methoxy-5-methylphenol. Yield=43%.
