Procedure
Methyl-3-[5-(4-methyl-piperazine-1-carbonyl)-pyridin-2-ylamino]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyridin-2-one (104 mg, 0.256 mmol), 2-[2-(tert-butyl-dimethyl-silanyloxymethyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-6-cyclopropyl-2H-isoquinolin-1-one (124 mg, 0.233 mmol), 2 mL dioxane, 200 μL DMF, and a 0.86 mg/μL solution of cesium carbonate in water (450 μL, 1.2 mmol) were charged into a 4 mL reaction vial fitted with a stir bar and septum. Sparged mixture with nitrogen for 5 min. Added [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) chloride 1:1 complex with dichloromethane (10 mg, 0.012 mmol). The reaction was sparged with nitrogen for 5 min. Sealed the vial and stirred at 90° 16 hr. Cooled to room temperature and filtered the reaction mixture through a 300 mg C18 cartridge. Washed the cartridge with 4 mL EtOAc, 4 mL water, and 4 mL EtOAc. Separated filtrate phases and washed the organic phase with 5 mL of water and 5 mL of brine. Dried the solution over Na2SO4 and concentrated in vacuo. Purified by C18 reverse phase flash chromatography (gradient elution, 10 to 95% acetonitrile +0.1% TFA/water +0.1% TFA). Added 1 mL of saturated NaHCO3 to the pooled product fractions and concentrated in vacuo. Extracted the remaining aqueous mixture with 2×10 mL CH2Cl2, dried over Na2SO4, and concentrated in vacuo to obtain 6-cyclopropyl-2-(2-hydroxymethyl-3-{1-methyl-5-[5-(4-methyl-piperazine-1-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridin-3-yl}-phenyl)-2H-isoquinolin-1-one as an off-white solid. (80 mg, 0.13 mmol). MS (ESI) 617 (M+H)+.
