実験手順

To a suspension of 4-(2,3-diaminobenzoyl)amino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (242 mg) in water (3 ml) was added cyanogen bromide (46 mg) at ambient temperature. The mixture was stirred at the same temperature for 2 hours and then allowed to stand at the same temperature overnight. To the reaction mixture was added saturated aqueous sodium bicarbonate solution and the solution was extracted with chloroform. The organic layer was washed with water, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin-layer chromatography (chloroform-methanol=10:1) to give 4-(2-amino-1 H-benzimidazol-4-yl)carbonylamino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (67 mg) as a powder.
