Versuchsvorschrift

To a solution of 1-(bromomethyl)-3-methoxy-5-methylbenzene (2.14 g) in acetone (80 mL) were added sodium hydrogen carbonate (1.05 g) and water (50 mL), and the mixture was heated under reflux for 18 hr. The reaction mixture was extracted with ethyl acetate, and the extract was washed with saturated brine. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (1.22 g) as a yellow oil.
