Versuchsvorschrift

A mixture of 1-{2-hydroxy-4-methyl-4-[3-(2-methyl-[1,3]dioxolan-2-yl)phenyl]-2-trifluoromethylpentyl}-1H-quinolin-4-one (0.35 g, 0.75 mmol), ethanol (24 mL), water (4.8 mL), and pyridinium p-toluenesulfonic acid (95 mg, 0.37 mmol) was heated to reflux for 3 hours, cooled to room temperature, and concentrated in vacuo to remove most of the ethanol. The residue was diluted with ethyl acetate and water. The aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with saturated aqueous sodium bicarbonate and brine, and dried over sodium sulfate. Removal of the volatiles in vacuo afforded 1-[4-(3-acetylphenyl)-2-hydroxy-4-methyl-2-trifluoromethylpentyl]-1-H-quinolin-4-one. Yield: 0.27 g (84%).
