Abstract
Process for the preparation of new derivatives of xanthine and their salts, characterized in that 1,3-dialcohyl-xanthines are reacted in an organic solvent at 100-150º c. With acrylic nitrile in the presence of basic catalysts and antipolymerizing agents and, optionally, hydrogenating the 1,3-dialcohil-7-cyanethyl-xanthines obtained under pressure and in the presence of hydrogenation catalysts.
