Reaction Steps
To a mixture of 2-bromo-3,6-dihydroxy-benzaldehyde (12A) (50 g, 0.23 mol) and hydroxylamine hydrochloride (19.2 g, 0.28 mol) was added 95% EtOH (500 mL), followed by NaOH (13.8 g, 0.345 mol). The reaction mixture was stirred at room temperature for 2 hours, then extracted with ethyl acetate and concentrated to give 2-bromo-3,6-dihydroxy-benzaldehyde oxime (12B) (45 g, 84.1% yield) as a solid.
