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 (200 mg) in water (5 ml) was added 1N hydrochloric acid (1.3 ml) and then dicyandiamide (545 mg) was added to the stirred reaction mixture. The solution was heated under reflux for 24 hours. After cooling, aqueous sodium hydrogen carbonate was added to the mixture and extracted with ethyl acetate. The extract was washed with brine and dried over sodium sulfate. After evaporation of the solvent, the residue was purified by silica gel column chromatography (SiO2, 30 g, 15% methanol in chloroform) to give 4-[2-guanidinobenzimidazol-4-yl]carbonylamino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (100 mg) as yellow amorphous.
