Reaction Steps

To a solution of 2-(6-methoxy-[1,5]naphthyridin-4-yl)-4,5,6,7-tetrahydro-2H-indazol-5-ylamine (30 mg, 0.1 mmol) in DMF (1 mL) were added K2CO3 (40 mg, 0.3 mmol) and 2-chloro-N-(3,5-difluoro-phenyl)-acetamide (20 mg, 0.1 mmol), and the mixture was stirred for 15 h. A catalytic amount of NaI was added and the mixture heated at 50° C. for 15 h. The mixture was diluted with EtOAc (25 mL), washed with brine (4×10 mL), dried (MgSO4) and concentrated. The resulting residue was purified on SiO2 (0-5% CH3OH/CH2Cl2) to provide 30 mg (64%) of the title compound as a pale yellow solid.
