Procedure

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 2-iodo-N-(4-(4-(oxetan-3-yl)piperazin-1-yl)phenyl)-9-((2-(trimethylsilyl)ethoxy)methyl)-9H-purin-6-amine 117f (360 mg, 0.60 mmol), {2-[(acetyloxy)methyl]-3-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}-5-fluorophenyl}boronic acid 110g (360 mg, 0.90 mmol), Pd(dppf)Cl2 (30 mg, 0.030 mmol), K3PO4 (270 mg, 1.2 mmol), sodium acetate (180 mg, 1.2 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 20:1 dichloromethane/methanol to afford 123a as a yellow solid (200 mg, 35%). MS-ESI: [M+H]+ 850.4
