(NE)-N-[(5-bromo-2-fluoro-3-methylphenyl)methylidene]hydroxylamine → 5-Bromo-2-fluoro-3-methyl-benzonitrile

Participants

Reaction Steps

A stirred solution of (E)-5-bromo-2-fluoro-3-methylbenzaldehyde oxime (0.5 g, 2.2 mmol) in acetic anhydride (5.0 mL) was heated to reflux for 18 h. The reaction mixture was diluted with water and extracted with ethyl acetate. The combined ethyl acetate layer was washed with brine and dried over Na2SO4 and concentrated under reduced pressure to afford the crude compound as a light brown gummy material (0.4 g, crude): ESIMS m/z 213.82 ([M+H]+).
