Procedure

To a solution of 4-(3-chloro 4-fluoro-phenyl)-1,3-dihydro-indol-2-one (65.4 mg, 0.25 mmol) and 2-formyl-5-methyl-1H-pyrrole-3-carboxylic acid (2-pyrrolidin-1-yl-ethyl)amide (64.8 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 2-[4-(3-chloro-4-fluoro-phenyl)-2-oxo-1,2-dihydro-indol-3-ylidenemethyl]-5-methyl-1H-pyrrole-3-carboxylic acid (2-pyrrolidin-1-yl-ethyl)amide as a yellow solid (89 mg, 72%).
