Procedure

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 (58 mg, 0.13 mmol), 2-(3-Bromo-phenyl)-6-dimethylamino-2H-isoquinolin-1-one (45 mg, 0.13 mmol), potassium phosphate (56 mg, 0.26 mmol), 2-(dicyclohexylphoshphino)-2′,4′,6′-tri-i-propyl-1,1′-biphenyl (3.7 mg, 0.0078 mmol), and bis(dibenzylidineacetone)palladium(0) (2.2 mg, 0.0038 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 2 hours. 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 preparative TLC (5% methanol/dichloromethane) to yield 6-Dimethylamino-2-(3-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridin-3-yl}-phenyl)-2H-isoquinolin-1-one (45 mg, 0.078 mmol). MS (ESI) 577.1 (M+H)+.
