実験手順

A mixture of 1-[4-(3-acetylphenyl)-2-hydroxy-4-methyl-2-trifluoromethylpentyl]-1-H-quinolin-4-one (60 mg, 0.14 mmol), potassium carbonate (79 mg, 0.57 mmol), and hydroxylamine hydrochloride (39 mg, 0.55 mmol) in methanol (1 mL) was heated at 65° C. for 3 hours, cooled to room temperature, and concentrated in vacuo. The residue was diluted with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, and concentrated in vacuo. The residue was purified by flash chromatography to afford 1-(2-hydroxy-4-{3-[1-(hydroxyimino)ethyl]phenyl)}-4-methyl-2-trifluoromethylpentyl)-1H-quinolin-4-one. Yield: 38 mg.
