Reaction Steps

Step-2: To a solution of (E)-methyl 1-acetyl-3-(ethoxy(phenyl)methylene)-2-oxo-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-6-carboxylate (2.6 g, 7.10 mmol) in DMF (5 mL) was added N-(4-aminophenyl)-N-methyl-2-(4-methylpiperazin-1-yl)acetamide (1.94 g, 7.43 mmol) at RT and the reaction mixture was heated to 110° C. and stirred for 1 h. The reaction mixture was allowed to cool to RT, treated with piperidine (3 mL) and stirred for 30 min. The reaction mixture was evaporated and the resultant 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[2,3-b]pyridine-6-carboxylate as yellow solid. MS (ES+): m/z 541.1 (MH+).
