Versuchsvorschrift

26.4 g (160 mmol) of 1-(3-nitrophenyl)ethanone are suspended in 270 ml of methanol, and 6.1 g (160 mmol) of sodium borohydride are added in portions with ice cooling. The reaction mixture is subsequently stirred for a further 3 h without cooling, diluted with 300 ml of dichloromethane and washed with 3×200 ml of water. The organic phase is dried over sodium sulfate and evaporated to dryness.
