Procedure

To a solution of 4-(4-bromo-phenyl)1,3-dihydro-indol-2-one (72 mg, 0.25 mmol) and 5-formyl-4-methyl-1H-pyrrole-3-carboxylic acid (2-diethylamino-ethyl) amide (62.8 mg, 0.25 mmol) in ethanol (2 mL) was added piperidine (3 drops). The reaction mixture was stirred at room temperature for three days. A yellow solid product was precipitated out, filtered, washed by ethanol for three times, and dried under high vacuum to provide pure product 5-[4-(4-bromo-phenyl)-2-oxo-1,2-dihydro-indol-3-ylidenemethyl]4-methyl-1H-pyrrole-3-carboxylic acid (2-diethylamino-ethyl)-amide (82 mg, 63%).
