Versuchsvorschrift

After 15 minutes 1-(4-chlorophenyl)-2-cyclopropylpropan-1-ol (44.72 g, 212 mmol) in dry dichloromethane (330 ml) was added over approximately 35 minutes. After 75 minutes triethylamine (154 ml), 1105 mmol) was added and the mixture allowed to warm to room temperature. Hexane was added and the mixture washed with 1M hydrochloric acid, saturated aqueous sodium bicarbonate solution and water, dried and evaporated in vacuo. Chromatography [SiO2, hexane-ethyl acetate (100:0) to (90:10)] gave 1-(4-chlorophenyl)-2-cyclopropylpropan-1-one (38.0 g, 86%).
