Reaction Steps

To a suspension of (6aR,8R,9S,9aS)-8-(6-chloro-9H-purin-9-yl)-2,2,4,4-tetraisopropyltetrahydro-6H-furo[3,2-f][1,3,5,2,4]trioxadisilocin-9-ol (300 mg, 0.57 mmol) and Cs2CO3 (1.86 g, 5.7 mmol) in DMF (5.7 mL) at 0° C. was added MeI (350 μL, 5.7 mmol) dropwise. The suspension was stirred for 3 hours, quenched with saturated aqueous NH4Cl and CH2Cl2. The layers were separated and the aqueous layer was extracted with CH2Cl2 (2×). The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. The crude material was purified by silica gel chromatography (0 to 20% EtOAc/hexanes) to afford 221 mg (71%) of the title compound.
