Reaction Steps

3-[3-(3,5-Dimethylpiperazin-1-yl)-3-oxo-propyl]-4,5,6,7-tetrahydro-1H-indole-2-carbaldehyde (136 mg, 0.3 mmol) was condensed with 5-methylaminosulfonyloxindole (68 mg, 0.3 mmol) following the same procedure used in Example 1 above to give 3-[1-{3-[3-(3,5-dimethyl-piperazin-1-yl)-3-oxo-propyl]-4,5,6,7-tetrahydro-1H-indol-2-yl}-meth-(Z)-ylidene]-2-oxo-2,3-dihydro-1H-indole-5-sulfonic acid methylamide (97 mg, 62% yield).
