[Researches on methyl-xanthine series.XI. Synthesis and physicochemical characterization of some 7-R-1,3-dimethyl-xanthine derivatives].
We have synthesized new xanthine compounds, derivatives of theophylline with various radicals in 7 position. The compounds have been characterized by molecular formula, weight, yield and melting point. The synthesized xanthine derivatives have been purified by repeated crystallizations from various organic solvents. Their chemical structure was confirmed by IR spectroscopy.
