Procedure

To a solution of 6-bromo-5-(2-fluoro-4-nitro-phenoxy)-1-(tetrahydropyran-2-yl)-1 H-indazole (8.0 g, 18 mmol) in tert-butanol (150 mL) and H2O (3.2 mL) is added Pd2(dba)3 (320 mg, 0.35 mmol), 2-di-tert-butylphosphino-2′-methylbiphenyl (480 mg, 1.54 mmol), KOH (3.2 g, 57 mmol) and morpholine (3.2 g, 36.7 mmol) under N2. After the mixture is stirred at 70° C. for 2 hours under a N2 atmosphere, it is filtered and the filtrate is concentrated. The residue is partitioned with EtOAc (100 mL) and saturated aqueous NH4Cl (30 mL). The organic layer is separated, dried over MgSO4, and concentrated. The residue is purified by silica gel column chromatography eluting with PE:EtOAc (3:1) to give the product (4.5 g, 56.5% yield). MS (m/z): 443.1 (M+H).
