Reaktionsschritte

A solution of sodium dithionite (95.4 g, 0.548 mols) in water (330 ml) was added to a solution of 2,3-dimethoxy-5-methyl-1,4-benzoquinone (50 g, 0.274 mols) in diethyl ether (330 ml), and shaken for 15 minutes. The ether layer was washed with a saturated aqueous sodium chloride solution, then dried and concentrated in vacuo. The resulting crystals were washed with hexane to obtain 2,3-dimethoxy-5-methyl-1,4-hydroquinone (46.1 g).
