The resulting solution was concentrated in vacuo and the residue was diluted with chloroform. The organic layer was washed successively with water and brine, dried over magnesium sulfate and concentrated in vacuo to give 4-[(2-hydroxyiminomethylindol-4-yl)carbonyl]amino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (203 mg).
