Procedure

A sealed tube was charged with the mixture of (2-{4,4-dimethyl-9-oxo-7-thia-10-azatricyclo[6.4.0.02,6]dodeca-1(8),2(6)-dien-10-yl}-4-fluoro-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methyl acetate 247b (300 mg, 0.584 mmol), 5-bromo-1-methyl-3-(5-(oxetan-3-yl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)pyridin-2(1H)-one 252a (222 mg, 0.584 mmol), Pd(dppf)Cl2 (48 mg, 0.0584 mmol), K3PO4.3H2O (311 mg, 1.168 mmol), and NaOAc (96 mg, 1.168 mmol) in CH3CN (20 mL). The system was evacuated and then refilled with N2. And the reaction mixture was heated at 110° C. for 2 h. Then, the mixture was 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 318a as a yellow solid (304 mg, 74%). MS: [M+H]+ 687.
