Versuchsvorschrift

To a stirred suspension of 8-(2,6-dichlorobenzoylamino)-4-hydrazinoquinoline (216 mg) in pyridine (2 ml) was added a solution of methanesulfonyl chloride (78.4 mg) in dimethylformamide under ice-cooling, and the mixture was stirred for 50 minutes at the same temperature. The mixture was concentrated in vacuo, and ethyl acetate, methanol and water were added to the residue. The separated organic layer was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography and recrystallized from ethanol to give 8-(2,6-dichlorobenzoylamino)-4-(2-methanesulfonylhydrazino)quinoline (16 mg).
