Versuchsvorschrift
To 112 g of 2-chloro-6,7-dimethoxy-3-quinolinecarboxaldehyde oxime was added 1000 ml of acetic anhydride. The mixture was stirred at reflux for 3 hours and then cooled to room temperature. The precipitate which formed was separated by filtration, washed with hot ethanol, and then dried to give 2-chloro-6,7-dimethoxy-3-quinolinecarbonitrile melting at about 223.5°-224.5° C.
