The present invention provides a method for producing an inosine derivative represented by the following general formula (1) including the steps of subjecting an inosine derivative of general formula (3) to dithiocarbonylation and carrying out radical reduction of the obtained compound. According to the present invention there can be produced compounds useful as anti-AIDS drugs on industrial scale. (see formula 1) (see formula 3) wherein R1 may be the same or different and are each benzyl group, benzhydryl group or trityl group, each of which may have a substituent in general formulas (1) and (3).

L'invention concerne un procédé permettant de produire un dérivé d'inosine représenté par la formule générale (1). Ce procédé consiste à dithiocarbonylater un dérivé d'inosine représenté par la formule générale (3) et à réduire le composé obtenu à l'aide d'un radical. Il est ainsi possible de produire à une échelle industrielle le composé cible, qui est utile en tant qu'agent antiviral. Dans les formules générales (1) et (3), les R1 peuvent être identiques ou différents et chacun représente benzyle, benzhydryle ou trityle éventuellement substitué.
