実験手順

49.5 g (0.263 mol) of 2,2,2-trifluoro-1-(4-methylphenyl)-ethanone are dissolved in 250 ml of ethanol at 80° C. To the solution are added dropwise 19.2 g (0.276 mol) of hydroxylammonium chloride and 36.7 g (0.447 mol) of sodium acetate dissolved in 125 ml of water. The reaction mixture is refluxed for 3.5 hours. The mixture is poured into ice water, affording a white solid. The filtration yields 39.2 g of 2,2,2-trifluoro-1-(4-methylphenyl)-ethanone oxime as a white solid, mp. 54-68° C. The crude product is used in the next step without further purification.
