6-Fluoro-N-[6-(1H-indol-4-yl)-1H-indazol-4-yl]-2-pyridinecarboxamide (50 mg, 0.14 mmol) and methyl(tetrahydro-2H-pyran-4-yl)amine (31 mg, 0.27 mmol) were dissolved in DMSO (0.5 ml) in a microwave vial. DIPEA (0.141 ml) was added and the mixture was heated at 160° C. for 4 h under microwave irradiation. The reaction mixture was diluted with MeOH (0.5 ml) and was purified by Mass Directed Automated Preparative HPLC (Method C). Fractions containing product were blown to dryness and the residue dissolved in methanol. This solution was loaded onto a 1 g aminopropyl column which was eluted with MeOH (1 column volume). The solvent was removed under a stream of nitrogen to give the title compound (17 mg) as a cream solid.
