To 7-chloro-6-fluoro-2-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)-2H-pyrazolo[4,3-b]pyridine (85 mg, 0.284 mmol) and 7-chloro-6-fluoro-1-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)-1H-pyrazolo[4,3-b]pyridine (85 mg, 0.284 mmol) in t-BuOH (4 mL) was added 3′-fluoro-5,6′-dimethyl-2,2′-bipyridin-4-amine (185 mg, 0.851 mmol), tri(dibenzylidene acetone)dipalladium(0) (26.0 mg, 0.028 mmol), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (27.0 mg, 0.057 mmol) and potassium carbonate (157 mg, 1.134 mmol) and the mixture was heated at 100° C. over night. The mixture was cooled and evaporated to give a residue which was partitioned between EtOAc (75 mL) and water. The layers were separated and the aqueous layer was extracted with EtOAc (75 mL). The combined organic layers were dried over Na2SO4, filtered, and concentrated to give a residue which was purified on HPLC using a gradient of 20-50% acetonitrile (containing 0.035% TFA) in water (containing 0.05% TFA) using a Sunfire Prep 5 μm C18, 75×30 mm column to give a residue. The residue was combined with 1N HCl (3 mL) and the solution was stirred for an hour, evaporated and lyophilized to give the title compound as a HCl salt. 1HNMR (400 MHz, DMSO-d6) δ ppm 2.52 (s, 3H) 2.58 (s, 3H) 3.80 (t, J=5.43 Hz, 2H) 4.47 (t, J=5.43 Hz, 2H) 7.28 (d, J=1.77 Hz, 1H) 7.57 (dd, J=8.59, 3.54 Hz, 1H) 7.82 (dd, J=11.37, 8.59 Hz, 1H) 8.52 (s, 1H) 8.74 (d, J=2.78 Hz, 1H) 8.87 (s, 1H) 10.16 (br. s., 1H).
