Sodium Carbonate → 7-tert-Butyl-3-(3-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridin-3-yl}-phenyl)-1H-quinolin-4-one

Participants

Reaction Steps

A solution of 5-Bromo-1-methyl-3-[5-(morpholine-4-carbonyl) -pyridin-2-ylamino]-1H-pyridin-2-one (19 mg, 0.050 mmol), 7-tert-Butyl-3-[3-(4,4,5,5-tetramethyl -[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-quinolin-4-one (20 mg, 0.05 mmol), tetrakis(triphenylphosphine)palladium(0) (6.0 mg, 0.0052 mmol), and sodium carbonate (16 mg, 0.15 mmol) in 2 mL 1,2-dimethoxyethane and 1 mL water was microwaved at 170° C. for 12.5 minutes. The resulting mixture 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 7-tert-Butyl-3-(3-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridin-3-yl}-phenyl)-1H-quinolin-4-one (5.7 mg, 0.0085 mmol). MS (ESI) 590.1 (M+H)+.
