Reaction Steps

To a solution of 4-[(indol-4-yl)carbonyl]amino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (93 mg) in dichloromethane (6.0 ml) was added N,N-dimethylmethylene- ammonium chloride (41.7 mg) at 0° C. and the mixture was stirred at ambient temperature for 1 hour. The resulting mixture was diluted with water and the aqueous solution was extracted with dichloromethane. Drying, filtering and removal of solvents afforded 4-[(3-dimethylaminomethylindol-4-yl)carbonyl]amino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (90 mg) as a colorless syrup.
