A mixture of 6-chloro-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[4,3-c]pyridine (0.80 g, 3.4 mmol) (Example 24, Step 1), 2-(3,5-dimethoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (1.1 g, 4.0 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complexed with dichloromethane (1:1) (200 mg, 0.3 mmol), and potassium phosphate (1400 mg, 6.7 mmol) in 1,4-dioxane (7 mL) and water (1 mL) in a reaction vial was degassed and sealed. It was stirred at 90° C. for 2 h. After cooling it was concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with ethyl acetate in hexanes (0-50%) to afford the desired product (660 mg). LCMS (M+H)+=340.1.
