Reaction Steps

A solution of 2,6-dichloro-N-[5-(3,5-difluorobenzyl)-1H-indazol-3-yl]pyridine-3-carboxamide (80 mg, 0.18 mmol) in dioxane (1 mL) was heated at 100° C. for 24 hours in the presence of DIPEA (0.1 mL, 0.55 mmol) and tetrahydro-2H-pyran-4-amine. (28 mg, 0.28 mmol) Reaction mixture was diluted with EtOAc and washed with water. The organic layer was dried over sodium sulfate, filtered and evaporated. The crude was purified by flash chromatography on silica gel using DCM/EtOH 95:5 as the eluant, affording 57 mg of the title compound.
