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

A solution of 6-Chloro-2-methyl-4-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]2H-pyridazin-3-one (56 mg, 0.16 mmol), 7-tert-Butyl-3-[2-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-3H-quinazolin-4-one (68 mg, 0.16 mmol), tetrakis(triphenylphosphine)palladium(0) (19 mg, 0.016 mmol), and sodium carbonate (52 mg, 0.49 mmol) in 2 mL 1,2-dimethoxyethane and 1 mL water was heated on the microwave synthesizer at 170° C. for 12.5 minutes. The resulting mixture was partitioned between ethylacetate and water. The ethylacetate layer was washed with brine, dried over anhydrous MgSO4, concentrated in vacuo, and purified by preparative TLC (10% MeOH/CH2Cl2) to yield 7-tert-Butyl-3-(2-methyl-3-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridazin-3-yl}-phenyl)-3H-quinazolin-4-one (26.4 mg, 0.044 mmol). MS (ESI) 606 (M+H)+.
