Methane → 2,4-Dimethylresorcinol

Participants

Reaction Steps

1 g (6.5 mmol) of 2,4-dihydroxy-3-methylbenzaldehyde is hydrogenated, at 3 bar hydrogen pressure for 24 h, with 100 mg of Pd on active charcoal (10%) in 100 ml of methanol and 1 ml of glacial acetic acid. A further 100 mg of Pd on active charcoal (20%) are added and the mixture is hydrogenated at 3 bar hydrogen pressure for 12 h. The catalyst is filtered off, the solvent is removed in vacuo and the residue is purified by chromatography (dichloromethane/acetone). 274 mg (30%) of 1,3-dihydroxy-2,4-dimethylbenzene are obtained.
