Versuchsvorschrift
0.826 g (21.8 mmol) of sodium borohydride was added to 2-bromo-4′-methoxy-acetophenone (10 g, 43.7 mmol) in methanol (200 ml) and the mixture was stirred for 1 hour at room temperature. The mixture was concentrated in vacuo and saturated aqueous sodium chloride was added to the residue and the product was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and concentrated in vacuo to give 2-bromo-1-(4′-methoxyphenyl) ethanol (11.05g).
