실험 절차
A mixture of 3,5-difluoro-4-formylbenzonitrile (500 mg, 3.0 mmol), hydroxylamine hydrochloride (207 mg, 3.0 mmol) and potassium acetate (586 mg, 6.0 mmol) in methanol (10 mL) was heated to 60° C. for 1 h then concentrated in vacuo and purified by column chromatography (eluent: DCM) to afford 3,5-difluoro-4-((hydroxyimino)methyl)benzonitrile (130 mg, 0.7 mmol) as a white solid.
