Reaction Steps
A suspension of 3-bromo-6-chloro-2-fluorobenzaldehyde (9.0 g, 0.04 mol) and hydroxylamine-O-sulfonic acid (7.50 g, 0.07 mole) in water (300 mL) was heated at 50° C. for eighteen hours. The suspension was cooled and the solid was collected to give 3-bromo-6-chloro-2-fluorobenzonitrile (8.8 g, 0.04 mol): 1H NMR (CDCl3): δ 7.75 (m, 1H), 7.25 (m, 1H).
