Versuchsvorschrift

To a solution of 3-fluoro-4-methoxybenzaldehyde (1 g, 6.5 mmol) in methanol (15 mL) was added under ice-cooling sodium borohydride (378 mg, 10 mmol) and the mixture was stirred at room temperature for 1 h. The solvent was evaporated under reduced pressure and the obtained residue was dissolved in ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give an almost pure title compound (1 g, 100%).
