Procedure

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with (4-fluoro-2-{6-oxo-8-thia-5-azatricyclo[7.4.0.02,7]trideca-1(9),2(7)-dien-5-yl}-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methyl acetate 103g (288 mg, 0.60 mmol), 2-iodo-N-(4-(4-(oxetan-3-yl)piperazin-1-yl)phenyl)-9-((2-(trimethylsilyl)ethoxy)methyl)-9H-purin-6-amine 117f (364 mg, 0.60 mmol), Pd(dppf)Cl2 (49 mg, 0.060 mmol), K3PO4 (254 mg, 1.20 mmol), sodium acetate (98 mg, 1.20 mmol), water (0.5 mL), and acetonitrile (10 mL). After three cycles of vacuum/argon flush, the 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 30:1 dichloromethane/methanol to afford 119a (307 mg, 60%). MS-ESI: [M+H]+ 853.4
