Reaction Steps

To a solution of (2R,3S,5R)-2-({[tert-butyl(dimethyl)silyl]oxy}methyl)-5-{6-[(1S)-2,3-dihydro-1H-inden-1-ylamino]-9H-purin-9-yl}tetrahydrofuran-3-yl acetate (440 mg, 0.84 mmol) in pyridine/tetrahydrofuran (1:1, 3.4 mL) was added approximately 20 drops of hydrofluoric acid in pyridine (2.0 M). After stirring for 17 h, the reaction was quenched with saturated aqueous NaHCO3 and extracted with dichloromethane. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification via flash chromatography (40 to 100% EtOAc/hexanes) afforded 314 mg (91%) of the title compound.
