The mixture was stirred at 55° C. for 1 hour. To the solution were added water and EtOAc and the mixture was extracted with EtOAc. The extract was washed with water, dried over MgSO4, filtrated and evaporated The residue was purified by column chromatography on silica gel with chloroform and methanol (100:0 to 90:10) to give 4-(cyclohexylamino)-N-methyl-1H-pyrrolo[2,3-b]pyridine-5-carboxamide (5 mg), as a pale yellow powder.
