Reaction Steps

A mixture of 4-(2,3-diaminophenyl)carbonylamino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (200 mg), glyoxal (47 mg) and sodium hydrogen sulfite (169 mg) in ethanol (15 ml) was refluxed for 5 hours. The solution was diluted with chloroform (30 ml) and the solution was washed with water and brine. The organic solution was dried over magnesium sulfate and the solvent was evaporated in vacuo to give an oil. The crude product was purified by silica gel column (1% methanol in chloroform) to give 3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]-4-(quinoxalin-5-yl)carbonylaminobenzamide (131 mg).
