Reaction Steps

A mixture of 2-benzyloxy-5-bromobenzaldehyde (20 g) and hydroxylamine hydrochloride (9.55 g) in pyridine (50 ml) was heated at 75° C. for 45 minutes. The solvent was evaporated and the residue purified by chromatography, eluting with dichloromethane, to give 2-benzyloxy-5-bromobenzaldehyde oxime (30 g) (mp 132°-134° C.).
