実験手順

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 120f (400 mg, 0.82 mmol), 2-iodo-N-(4-(4-(oxetan-3-yl)piperazin-1-yl)phenyl)-9-((2-(trimethylsilyl)ethoxy)methyl)-9H-purin-6-amine 117f (604 mg, 0.99 mmol), PdCl2(dppf) (33 mg, 0.040 mmol), K3PO4 (347 mg, 1.64 mmol), and sodium acetate (134 mg, 1.64 mmol), acetonitrile (15 mL), and water (1 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 30:1 dichloromethane/methanol to afford 120g (460 mg, 66%) as a green solid. MS-ESI: [M+H]+ 836.4.
