Versuchsvorschrift

56 parts of 3,7-dichloro-8-dichloromethylquinoline in 250 parts of 90% strength sulfuric acid were stirred at 100° C. for 6 hours. After cooling, the solution was poured onto ice and the precipitated solid was filtered off with suction, washed neutral with water and dried. 195 parts of 3,7-dichloroquinoline-8-carbaldehyde of melting point 208° C. were obtained. The yield corresponds to 87% of theory.
