반응 단계
A solution of 3-(p-Chlorophenyl)-1,1,1-trifluoro-2-propanone (10.0 g, 0.045 mol) and ethanol (60 mL) is treated with a solution of hydroxylamine hydrochloride (4.68 g, 0.067 mol) and water (20 mL) and then with a solution of sodium acetate (5.53 g, 0.067 mol) and water (20 mL). The reaction mixture is then refluxed for 2 hours, cooled to room temperature, diluted with water and extracted with ether. The combined organic extracts are washed sequentially with water and brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give a liquid which solidifies upon standing to give the title product as white needles (11.84 g). Identified by IR and NMR spectral analyses.
