Procedure

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 (160 mg) in N,N-dimethylformamide (3.0 ml) was added portionwise potassium tert-butoxide (37.3 mg) at 0° C. and the mixture was stirred at 0° C. for 1 hour. Methyl iodide (47.2 mg) was added to the mixture and the solution was stirred at 0° C. for 1 hour. The reaction was quenched with water and then the aqueous solution was extracted with ethyl acetate. Drying, filtering and removal of solvents afforded a crude product. The crude product was purified by column chromatography (eluent; 2% methanol in chloroform) to give 4-[(1-methylindol-4-yl)carbonyl]amino-3-methoxy-N-methyl-N-[4-methyl-2-[5-(4-methylpiperazin-1-yl)carbonylpent-1-yloxy]phenyl]benzamide (65 mg) as a white syrup.
