Procedure
To a solution of (2R,3R,5S)-5-hydroxymethyl-2-[6-((S)-indan-1-ylamino)-purin-9-yl]tetrahydrofuran-3-yl acetate (0.20 mmol) and triethylamine (56 μL, 0.0.40 mmol) in DMF (3.3 mL) was added dropwise 150 μL of a 2M solution of the chlorosulfonamide in acetonitrile and the cloudy solution was stirred. Identical amounts of triethylamine and the chlorosulfonamide solution were added after 2.5 and 4 hours. The reaction was diluted with EtOAc and water, the layers were separated, and the aqueous layer was extracted with EtOAc (1×). The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude material was purified by silica gel chromatography (0% to 10% MeOH/CH2Cl2) to afford 51 mg (52%) of the title compound.
