Reaction Steps
A solution of 4,4,4-trifluoro-3-hydroxy-1-(4-methylphenyl)-3-[3-(trifluoromethyl)phenyl]butan-1-one (1.0 g), hydroxylamine hydrochloride (0.28 g) and pyridine (0.42 g) in ethanol (10 mL) was heated to reflux for 5 hours. After the reaction solution was diluted with t-butylmethylether, the solution was washed with water and saturated brine. The organic layer was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to yield 4,4,4-trifluoro-3-hydroxy-1-(4-methylphenyl)-3-[3-(trifluoromethyl)phenyl]butan-1-one oxime (1.0 g).
