Versuchsvorschrift

To a mixture of 3,4-diethoxybenzaldehyde (6.68 g) and methanol (100 ml) was added sodium borohydride (1.30 g) at 0° C. The resulting mixture was stirred at 0° C. for 45 minutes. The reaction mixture was mixed with water and was extracted with ethyl acetate. The organic layer was washed with an aqueous saturated solution of sodium chloride and was dried with anhydrous magnesium sulfate. The resulting organic layer was evaporated under reduced pressure to remove the solvent to obtain 3,4-diethoxybenzyl alcohol (6.64 g) as a yellow oil.
