Versuchsvorschrift

2-Benzyloxy-3-methylbenzaldehyde prepared by the above 2-(1) 20.0 g (88.4 mmol) was dissolved in methanol 100 ml and thereto was added sulfuric acid 20.0 g (203 mmol) and then added 30% hydrogen peroxide 30.1 g (265 mmol). The mixture was refluxed for 2 hours. After disappearance of the raw material, the solution was concentrated in vacuo, neutralized with a saturated sodium bicarbonate solution and extracted with methylene chloride. The solvent was removed in vacuo and the residue was purified by silica gel chromatography (n-hexane-ethyl acetate) to give 2-benzyloxy-3-methylphenol 13.3 g (yield: 70%).
