There is disclosed a process for synthesizing 2′-fluoro-2′,3′-dideoxyarabinofuranose derivatives of inosine and adenine on a large scale which involves coupling of a fluorosugar derivative and a purine reactant to provide a purine nucleoside intermediate which is then deoxygenated. 6-Chloro or 6-benzamidopurine and 1,3,5-tri-O-benzoyl-2-deoxy-2-fluoroarabinofuranose are used as starting materials.
