Procedure

A round-bottomed flask equipped with a reflux condenser was charged with 5-bromo-1-methyl-3-(5-methyl-1H-pyrazol-3-ylamino)pyridin-2(1H)-one 218a (201 mg, 0.71 mmol), {3-[(acetyloxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (282 mg, 0.71 mmol), Pd(dppf)Cl2 (51 mg, 0.07 mmol), K3PO4 (301 mg, 1.42 mmol), sodium acetate (116 mg, 1.42 mmol), acetonitrile (10 mL), and water (0.2 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 3 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 1:20 methanol/dichloromethane to afford 260a as a red solid (150 mg, 38%). MS-ESI: [M+H]+ 556.3
