Abstract
A process for the preparation of 2-fluoro-9- (2,3,5-tri-O-benzyl-beta-D-arabinofuranosyl)adenine (I) is described. The process involves reacting a protected 2-fluoro adenine with a protected chlorosugar under controlled conditions of temperature (80-85.degree. C.) to produce (I), rather than using a process involving fluorinating a 2-substituted nucleoside precursor of (I).
