実験手順
An excess of zinc powder was added to a stirred mixture of 3,5-difluoro-4-((hydroxyimino)methyl)benzonitrile (130 mg, 0.7 mmol) in acetic acid (10 mL) then heated to 60° C. for 2 h. The mixture was made basic by addition of aqueous ammonia and extracted with ethyl acetate. The organic layer was washed with brine, dried (Na2SO4) and concentrated in vacuo to afford 4-(aminomethyl)-3,5-difluorobenzonitrile (100 mg, 0.6 mmol) as a colourless oil.
