Reaction Steps

A mixture of 6-chloro-3-(1-methyl-1H-pyrazol-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[4,3-c]pyridine (0.06 g, 0.2 mmol), 2-(3,5-dimethoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.060 g, 0.23 mmol), [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II) complex with dichloromethane (1:1) (10 mg, 0.02 mmol), and potassium phosphate (80. mg, 0.38 mmol) in 1,4-dioxane (0.5 mL) and water (0.07 mL) in a reaction vial was degassed and sealed. The mixture 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 (80 mg). LCMS (M+H)+=420.2.
