A mixture of 3,4-dichloroacetophenone (1.0 eq), pyridine (5.0 eq) and hydroxylamine (5.0 eq) in EtOH (10 vol) was heated to a temperature of 90° C. for 80 minutes. To the cooled reaction mixture was added water (40 vol) and the precipitated solid was filtered, washed with water (2×10 vol) and dried to give 1-(3,4-dichloro-phenyl)-ethanone oxime.
