Procedure

To a sealed tube were added 2,6-dichloropurine-9-vinyl purine (0.43 g, 2 mmol), 4-aminophenyl-dimethylphosphine oxide (0.37 g, 2.2 mmol), and the solids were dissolved in ˜15 mL anhydrous EtOH under Ar. Then DIEA (1.0 mL, 6 mmol) was added. The reaction was heated at 105° C. for 3 overnights until the starting material 2,6-dichloro-9-vinylpurine had disappeared. Volatiles were removed by rotavaporing and the residue was partitioned between EtOAc/water. The organic layer was washed with water once more and dried over Na2SO4. The final product was purified by silica gel column chromatography (4˜8% MeOH/DCM).
