Abstract

The method of preparation of oxetanocin derivative of formula I consists in the fact that the compound of general formula III, where X1 means protected hydroxyl group or atom of halogen and R1 means protecting group, reacts with ammoniac in presence of inert solvent at a temperature of 0 to 200 degrees C. The compound of general formula I, as well as its physiologically acceptable salts, has mainly immunosuppressive and antiviral effects.<IMAGE>
