Procedure

To a solution of N-{3-[4-(bromomethyl)-2,6-dichlorobenzoyl]-1H-pyrrolo[2,3-c]pyridin-7-yl}cyclopropanecarboxamide (50 mg, 0.11 mmol) in acetonitrile, cesium carbonate (70 mg, 0.21 mmol) was added and stirred at same temperature. Methyl amine (6.8 mg, 0.21 mmol) was added at 0° C. The reaction mixture was then stirred at room temperature for 3 h. On completion, the reaction mixture was diluted with water and extracted with ethyl acetate, organic layer was separated, washed with brine, dried over sodium sulfate and concentrated under vacuum. Purification by silica gel (100-200) column chromatography using dichloromethane and methanol gradient as eluent afforded N-(3-{2,6-dichloro-4-[(methylamino)methyl]benzoyl}-1H-pyrrolo[2,3-c]pyridin-7-yl)cyclopropanecarboxamide (7.2 mg, 16%).
