Reaction Steps

A sealed tube was charged with the mixture of (2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methyl acetate (335 mg, 0.7 mmol), 5-bromo-1-methyl-3-(5-(4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)pyridin-2(1H)-one 188e (294 mg, 0.7 mmol), Pd(dppf)Cl2 (33 mg, 0.04 mmol), K3PO4.3H2O(372 mg, 1.4 mmol), and NaOAc (115 mg, 1.4 mmol) in CH3CN (20 mL). The system was evacuated and refilled with N2. The reaction mixture was heated at 110° C. for 2 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by flash column chromatography eluting with 30:1 methylene chloride/methanol to afford 311a as a yellow solid (208 mg, 43%). MS: [M+H]+ 692.
