Reaction Steps

2-Methoxy-5-phenoxybenzaldehyde (4.5 g, 19.7 mmol) was dissolved in 60 ml of warm methanol. Water (40 ml) was added to this solution followed by the addition of hydroxylamine hydrochloride (2.7 g, 38.9 mmol) and anhydrous sodium acetate (6.5 g, 79.2 mmol). This mixture was then refluxed for 4 hours. The reaction mixture was concentrated under reduced pressure to remove the methanol. The residue was partitioned with ethyl acetate. The ethyl acetate layer was separated, washed five times with water, dried (anhydrous MgSO4) and the solvent removed under reduced pressure to give 2-methoxy-5-phenoxybenzaldehyde oxime as a white crystalline solid (4.70 g, 98%), mp 95°-100° C.
