Versuchsvorschrift

To the solution of 5-bromoindolin-2-one (262 mg, 1.24 mmol) in EtOH (5 ml) was added N-(2-(diethylamino)ethyl)-5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxamide (298 mg, 1.12 mmol) and piperidine (112 μL, 1.13 mmol). The mixture was stirred at 80° C. for 1 hour. After cooled down to room temperature, the reaction mixture was concentrated, filtrated, and washed with EtOH to give (Z)-5-((5-bromo-2-oxoindolin-3-ylidene)methyl)-N-(2-(diethylamino)ethyl)-2,4-dimethyl-1H-pyrrole-3-carboxamide (368 mg) as orange solid.
