Versuchsvorschrift

β-Phenylpropiophenone (6-1) (7.5 g, 36.0 mmol) was suspended in ethanol (100 ml) and sodium borohydride (0.68 g, 18.0 mmol) was added under N2. The resulting solution was stirred at ambient temperature overnight. The ethanol was removed in vacuo and the residual oil-solid was taken up in ethyl acetate (100 ml) and water (30 ml). The ethyl acetate layer was removed, washed with water, dried, filtered and concentrated in vacuo to give 6-2 as a colorless oil.
