(2R,3S,4R,5R)-2-(6-Bromo-9H-purin-9-yl)-5-{[(triisopropylsilyl)oxy]methyl}-tetrahydrofuran-3,4-diyl diacetate (0.402 g, 0.703 mmol) was stirred in ethanol (10 mL) and S-(+)-1-aminoindan (0.14 mL, 1.06 mmol) was added followed by triethylamine (0.2 mL, 1.41 mmol). The reaction mixture was heated at overnight. The brown solution was concentrated and purified by flash chromatography, eluting with 10 to 35% ethyl acetate/hexanes to give the title compound as a white solid (0.142 g) and deacylated product (0.161 g, 37%).
