Procedure
N6 -(2,2-Diphenylethyl)adenosine (4.6 g, 0.01 mole) and acetic anhydride (2.9 mL, 306 mol %) are mixed in pyridine at room tempreature under nitrogen for 20 hours, and the reaction is evaporated in vacuo. The residue is dissolved in chloroform, washed twice with aqueous ice-cold 5% sodium carbonate, and the organic layer is dried (MgSO4) and evaporated in vacuo. Chromatography over silica gel eluting with 5/1 chloroform/methanol affords the title compound after evaporation in vacuo of appropriate fractions; mp 75°-80° C.
