Versuchsvorschrift

To a solution of 4-(3-fluoro-phenyl)1,3-dihydro-indol-2-one (56.8 mg, 0.25 mmol) and 5-formyl-4-methyl-1H-pyrrole-2-carboxylic acid (2-diethylamino-ethyl)-amide (65.3 mg, 0.26 mmol) in ethanol (2 mL) was added piperidine (3 drops). The reaction mixture was stirred at room temperature for three days. The reaction solution was evaporated, and purified on a silica gel column eluting with MeOH—CH2Cl2 5:95 to provide pure product 5-[4-(3-fluoro-phenyl)2-oxo-1,2-dihydro-indol-3-ylidenemethyl]4-methyl-1H-pyrrole-2-carboxylic acid (2-diethylamino-ethyl)-amide as a yellow solid (26 mg, 23%).
