A mixture of Compound (1) (50 mg, 0.11 mmol), potassium carbonate (30 mg, 0.22 mmol), copper(I) iodide (10 mg, 0.05 mmol), copper (6.9 mg, 0.11 mmol) and 4-fluorophenol (18 mg, 0.16 mmol) in pyridine (1 mL) was heated to 150° C. for 16 h in a sealed-tube. After cooling to RT, MeOH (5 mL) was added and the mixture was filtered through celite and washed with more MeOH. The filtrate was concentrated in vacuo to give a crude mixture which was purified by reverse phase flash column chromatography eluting with ACN/water (10-100%) to give 5-cyclopropyl-2-[4-(4-fluorophenoxy)phenyl]-N-methyl-6-[(methylsulfonyl)amino]-2H-indazole-3-carboxamide (2) (9 mg, 17%) as a pale yellow solid. ESI-MS m/z calculated for [M+H]+: 495.15; found: 495.12.
