Versuchsvorschrift

2-Benzyloxy-3-methylbenzaldehyde prepared by the above 2-(1) 20.0 g (88.4 mmol) was dissolved in methylene chloride 100 ml and thereto was added m-chloroperbenzoic acid 16.8 g (97.2 mmol). The mixture was reacted at 20° C. under stirring for 10 hours. After disappearance of the raw material, the solution was neutralized with a saturated sodium bicarbonate solution and extracted with methylene chloride. To the extract (2-benzyloxy-3-formyloxytoluene) was added a 10% sodium hydroxide solution 38.9 g (97.2 mmol) in the ice bath and the mixture was stirred for 3 hours. The reaction mixture was neutralized with a 5% hydrochloric acid solution and extracted with methylene chloride. The solvent was removed in vacuo and the residue was purified in the same manner as in the above mentioned 3-(1) to give 2-benzyloxy-3-methylphenol 16.7 g (yield: 88%).
