実験手順

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 (43 mg, 0.097 mmol), Acetic acid 2-bromo-6-(6-dimethylamino-1-oxo-1H-isoquinolin-2-yl)-benzyl ester (40 mg, 0.097 mmol), potassium phosphate (41 mg, 0.19 mmol), 2-(dicyclohexylphoshphino)-2′,4′,6′-tri-i-propyl-1,1′-biphenyl (2.7 mg, 0.0057 mmol), and bis(dibenzylidineacetone)palladium(0) (1.6 mg, 0.0028 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 5% methanol/dichloromethane) to yield Acetic acid 2-(6-dimethylamino-1-oxo-1H-isoquinolin-2-yl)-6-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridin-3-yl}-benzyl ester (33 mg, 0.051 mmol). MS (ESI) 649.2 (M+H)+.
