Versuchsvorschrift

A solution of 2,6-dichloro-4-trifluoromethylphenylhydrazine (10.2 g) in ether (15 ml) was added with cooling to a solution of `2-oxopropanal 1-oxime (3.62 g) in ether (15 ml) at 0°. The mixture was stirred at room temperature overnight and magnesium sulphate and charcoal added. The mixture was filtered and solvent evaporated under reduced pressure. The residue was purified by column chromatography to give 2-(2,6-dichloro-4-trifluoromethylphenylhydrazono)propanal 1-oxime, m.p, c.108°.
