Versuchsvorschrift
To a stirred solution of 4-(3-aminophenylamino)-6,7-dimethoxy-3-quinolinecarbonitrile (0.96 g, 3.0 mmol) in 9.0 ml of acetic acid at 25° C. was added 0.85 ml (9.0 mmol) of acetic anhydride. After 2 h the solution was evaporated to dryness, and the residue was stirred with methanol. This solution was evaporated, and the residue was recrystallized from ethanol to give 0.50 g of amber solid, mp 147-150° C.
