Reaction Steps

A mixture of 4-(2,3-diaminobenzoyl)amino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (150 mg) and diphenyl N-sulfamoylcarbonimidate (85 mg) in dichloromethane (8 ml) was refluxed for 24 hours under nitrogen. The reaction mixture was poured into water and extracted with chloroform. The organic layer was washed with water, driver over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin-layer chromatography (chloroform:methanol=10:1/chloroform:methanol=6:1) to give 3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]-4-(2-sulfamoylamino-1H-benzimidazol-4-yl)carbonylaminobenzamide (38 mg).
