To a solution of 4-phenyl-1,3-dihydro-indol-2-one (41.9 mg, 0.20 mmol) and 3,5-dimethyl-4-(4-methyl-piperazine-1-carbonyl)-1H-pyrrole-2-carbaldehyde (49.9 mg, 0.20 mmol) in ethanol (1 mL) was added piperidine (0.1 mL). The reaction mixture was stirred at 70° C. for over-night. The solvent was evaporated and the residue was crystallized from EtOAc-hexanes to provide 3-[3,5-dimethyl-4-(4-methyl-piperazine-1-carbonyl)-1H-pyrrol-2-ylmethylene]-4-phenyl-1,3-dihydro-indol-2-one as a yellow solid (50 mg, 57%).
