Reaction Steps

To a solution of 9-[(3aR,4R,6R,6aR)-6-({[tert-butyl(dimethyl)silyl]oxy}methyl)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl]-6-(2-methoxyethyl)-9H-purine (70 mg, 0.15 mmol) in THF/pyridine (1.5 mL, 1:1) was added hydrofluoric acid in pyridine (15 drops). The reaction was stirred overnight, quenched with saturated aq NaHCO3, extracted with EtOAc, dried (Na2SO4), filtered and concentrated. The residue was purified by flash chromatography (0 to 50% DCM/EtOAc to furnish 37 mg (70%) of the title compound.
