New theophylline and theobromine derivatives are synthesized from the β phenylethylaminoalkyl xanthines, whose phenyl substituent is substituted by one or two hydroxyl groups and partially also by other substituents. Different methods of synthesis are described, among them the production of the bronchospasmolytic 7 (3 [2 (3,5 dihydroxyphenyl) 2 hydroxy ethylamino] propyl) theophylline (reproterol . HCl).
