Reaction Steps

To 1-Methyl-3-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyridin-2-one (69 mg, 0.16 mmol), 2-(3-Bromo-2-methyl-phenyl)-6-dimethylamino-2H-isoquinolin-1-one (36 mg, 0.10 mmol), potassium phosphate (43 mg, 0.20 mmol), 2-(dicyclohexylphoshphino)-2′,4′,6′-tri-i-propyl-1,1′-biphenyl (2.9 mg, 0.0061 mmol), and bis(dibenzylidineacetone)palladium(0) (1.7 mg, 0.0030 mmol) was added 4 mL of degassed 1:3 water/n-butanol. The headspace of the vessel was evacuated and backfilled with argon 4 times. This was heated at 100° C. for 110 minutes. This was partitioned between ethyl acetate and water. The ethyl acetate layer was washed with brine, dried over anhydrous magnesium sulfate, concentrated in vacuo, and purified by flash chromatography (gradient elution 2 to 10% methanol/dichloromethane) to yield 6-Dimethylamino-2-(2-methyl-3-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridin-3-yl}-phenyl)-2H-isoquinolin-1-one (46 mg, 0.078 mmol). MS (ESI) 591.1 (M+H)+.
