Versuchsvorschrift

56 parts of 3,7-dichloro-8-dichloromethylquinoline in 250 parts of 90% strength sulfuric acid were stirred for 6 hours at 100° C. The solution was cooled and then poured onto ice, and the precipitated solid was filtered off under suction, washed neutral with water and dried to give 39 parts (87% of theory) of 3,7-dichloroquinoline-8-carbaldehyde of melting point 208° C.
