A solution in 3:1 ethanol-pyridine of 2-[(2,6-dichloro-3-methylphenyl)amino]benzaldehyde, prepared as in Example 1, steps 1-2, and O-allyl hydroxylamine(1.3 eq) was heated at reflux for 2 days. The reaction mixture was poured into ethyl acetate and the mixture was extracted with 10% aqueous HCl. Chromatography on silica gel (20% CH2Cl2 /hexanes) gave 2-[(2,6-dichloro-3-methylphenyl)amino]benzaldehyde-O-allyl oxime (1.13 g, 94%).
