実験手順: Step-2: To a solution of (E)-methyl 1-acetyl-3-(ethoxy(phenyl)methylene)-2-oxo-2,3-dihydro-1H-pyrrolo[3,2-c]pyridine-6-carboxylate (40 mg, 0.109 mmol) in DMF (0.2 mL) was added N-(4-aminophenyl)-N-methyl-2-(4-methylpiperazin-1-yl)acetamide (28 mg, 0.109 mmol) at room temperature, and the reaction mixture was stirred at 110° C. for 2 h. The reaction mixture was cooled to RT, piperidine (0.2 mL) was added and stirred for 10 minutes at room temperature. The solvent was evaporated and the resulting residue was purified by silica gel column chromatography using 5% CH3OH in dichloromethane as eluent to afford (Z)-methyl 3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylene)-2-oxo-2,3-dihydro-1H-pyrrolo[3,2-c]pyridine-6-carboxylate as yellow solid. MS (ES+): m/z 541.3 (MH+). The reaction mixture was cooled to RT stirred for 10 minutes at room temperature The solvent was evaporated the resulting residue was purified by silica gel column chromatography

実験手順: 10.5 g (30.0 mmol) of 1-acetyl-3-(1-ethoxy-1-phenylmethylene)-6-methoxycarbonyl-2-indolinone (for preparation see WO 01/27081 mentioned above) and 8.60 g (33.0 mmol) N-[(4-methyl-piperazin-1-yl)-methylcarbonyl]-N-methyl-p-phenylenediamine (for preparation see WO 01/27081 mentioned above) are dissolved in 80 mL of dimethylformamide and stirred for 1 hour at 80° C. After cooling 6.50 mL of piperidine are added and the mixture is stirred for another two hours at ambient temperature. Water is added, the precipitate formed is suction filtered and washed with a little water. The residue is suspended in 200 mL of methanol, suction filtered and washed with cold water and diethyl ether. The substance is dried in vacuo at 110° C. are added the mixture is stirred for another two hours at ambient temperature the precipitate formed filtered washed with a little water suction filtered washed with cold water and diethyl ether The substance is dried in vacuo at 110° C.
