In order to improve the oral bioavailability of Adenine 9-beta-D-arabinofuranoside (Vidarabine, also called ara A), an antiviral drug which is active against herpes simplex and varicella zoster viruses and the first agent to be licensed for the treatment of systematic herpes virus infection in man, the corresponding 5'-O-D-valyl ester derivative has been synthesized. Based on their physicochemical properties, 5'-O-valyl ara A has emerged as a potential prodrug candidate to improve the oral bioavailability of vidarabine. We describe in this paper a facile synthesis route for the prodrug and its physicochemical properties.
