Procedure

To a solution of 4-(3-fluoro-phenyl)-1,3-dihydro-indol-2-one (56.8 mg, 0.25 mmol) and 5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (3-diethylamino-propyl)-amide (69.8 mg, 0.26 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-(3-fluoro-phenyl)2-oxo-1,2-dihydro-indol-3-ylidenemethyl]-2.4-dimethyl-1H-pyrrole-3-carboxylic acid (3-diethylamino-propyl)amide as a yellow solid (57.3 mg, 47%).
