The title compound was prepared as described in example 161 using 3-bromo-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (1.7 g, 5.55 mmol), in ethylene glycol dimethyl ether (60 mL), 3-amino boronic acid (1.72 g, 11.10 mmol), [1,1′-bis(diphenylphosphino)-ferrocene] complex with dichloromethane (1:1) (0.641 g, 0.555 mmol), and potassium phosphate (5.89 g, 27.75 mmol). A second batch was prepared using 3-bromo-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (2.0 g, 6.53 mmol), in ethylene glycol dimethyl ether (70 mL), 3-amino boronic acid (2.025 g, 13.06 mmol), [1,1′-bis(diphenylphosphino)-ferrocene] complex with dichloromethane (1:1) (0.755 g, 0.653 mmol), and potassium phosphate (6.92 g, 32.65 mmol). The crude compounds were combined and purified by column chromatography using 30% ethyl acetate in hexanes (3.2 g, 82% yield): ES-MS (m/z) 319 [M+H]+.
