Procedure

A 50-mL single-neck round-bottomed flask equipped with a reflux condenser was charged with 5-bromo-1-methyl-3-(5-(1-methylazetidin-3-yloxy)pyridin-2-ylamino)-pyridin-2(1H)-one 206f (108 mg, 0.40 mmol), {3-[(acetyloxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diaza-tricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (240 mg, 0.60 mmol), Pd(dppf)Cl2 (20 mg, 0.02 mmol), K3PO4 (180 mg, 0.80 mmol), sodium acetate trihydrate (120 mg, 0.80 mmol), water (0.5 mL), and acetonitrile (10 mL). The system was evacuated and refilled with N2. The reaction mixture was heated at 100° 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 silica-gel column chromatography eluting with 10:1 dichloromethane/methanol to afford 207a (100 mg, 45%) as a yellow brown solid. LCMS-ESI: [M+H]+ 638.4.
