Versuchsvorschrift

4.25 g (10 mmol) (Z)—N-[2-(diethylamino)ethyl]-2-methyl-7-(1,2-dihydro-5-fluoro-2-oxo-3H-indol-3-ylidene)-4,5,6,7-tetrahydro-1H-indol-3-carboxamide was added to a mixture of 250 ml acetonitrile and 50 ml dichloromethane. The mixture was treated under ultrasonic sound to uniform dispersion. 1.19 g (12 mmol) concentrated sulfuric acid was added and the solution was heated to reflux with stirring under nitrogen atmosphere. After reaction for 1 h, the resulting solution was filtered while being hot, and the filtrate was concentrated at reduced pressure to dryness, added to 30 ml anhydrous ethanol and treated under ultrasonic sound to uniform dispersion. Then the solution was filtered, and the filter cake was dried at 40° C. under vacuum, to give the title compound as yellow solid (4.60 g, 8.8 mmol, yield 88%).
