Reaction Steps

In a fashion similar to that for preparation 13, 2,4-difluorobenzaldehyde (5.00 g, 35.2 mmol), hydroxylamine hydrochloride (2.94 g, 42.3 mmol), NaOH (7.04 g, 88.0 mmol; as a 50% solution by weight in water), ethanol (15 ml), H2O (15 ml), and ice (30 g) gave 2,4-difluorobenzaldehyde oxime (4.62 g, 84%) which was used without purification.
