Procedure

The solution of 5-(2-fluoro-4-nitrophenoxy)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-6-carboxylic acid (0.5 g, 1.25 mmol), tetrahydropyran-4-ylamine (0.13 g, 1.25 mmol), EDCI (0.24 g, 1.25 mmol), HOBT (0.17 g, 1.25 mmol), N-methylmorpholine (0.5 mL) in DMF (5 mL) is stirred at RT overnight. Then the reaction mixture is partitioned with saturated aqueous NH4Cl (20 mL) and EtOAc (50 mL). The organic phase is separated, dried over MgSO4, and concentrated. The residue is purified by silica gel column chromatography eluting with PE:EtOAc (1:1) to provide the product (0.49 g, 81.2% yield). MS (m/z): 485.1 (M+H).
