실험 절차
A mixture of 3.4 g (12.8 mmol) of 1-[4-(4-chloro-2-fluoro-phenoxy)-phenyl]-ethanone and 3.0 mL hydroxylamine solution (50% in water) in 100 mL ethanol was refluxed for five hours. Then the mixture was evaporated to dryness, the residue was combined with approx. 15 mL water and extracted three times with 10 mL ethyl acetate. The extracts were washed with saturated sodium chloride solution, dried and evaporated down. The product thus obtained was reacted further without any further purification.
