Procedure

A sealed tube was charged with the mixture of 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 (275 mg, 0.7 mmol), (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 131a (356 mg, 0.7 mmol), Pd(dppf)Cl2 (59 mg, 0.07 mmol), K3PO4.3H2O(317 mg, 1.4 mmol), and NaOAc (118 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 317a as a yellow solid (300 mg, 61%). MS: [M+H]+ 669.
