Versuchsvorschrift

5-Formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-ethylamino-ethyl)-amide (99 g), ethanol (400 mL), 5-fluoro-2-oxindole (32 g) and pyrrolidine (1.5 g) were refluxed for 3 hours with stirring. The mixture was cooled to room temperature and the solids collected by vacuum filtration. The solids were stirred in ethanol at 60° C., cooled to room temperature and collected by vacuum filtration. The product was dried under vacuum to give 5-[5-fluoro-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-ethylamino-ethyl)-amide (75 g, 95% yield). 1H-NMR (dimethylsulfoxide-d6) δ 1.03 (t, 3H, CH3), 2.42, 2.44 (2×s, 6H, 2×CH3), 2.56 (q, 2H, CH2), 2.70, 3.30 (2×t, 4H, 2×CH2), 6.85, 6.92, 7.58, 7.72, 7.76 (5×m, 5H, aromatic, vinyl and CONH), 10.90 (br s, 1H, CONH), 13.65 (br s, 1H, pyrrole NH).
