Reaction Steps
A mixture of 4-pyridin-3-yl-1,3-dihydroindol-2-one (42 mg, 0.2 mmol), 5-formyl-2-methyl-4-[3-(4-methylpiperazin-1-yl)-propyl]-1H-pyrrole-3-carboxylic acid ethyl ester (64 mg, 0.2 mmol) and piperidine (0.1 mL) in ethanol was heated in a sealed tube at 70° C. for 5 hours. The reaction was concentrated and the residue was purified by column chromatography to give the title compound.
