Abstract
Process for the preparation of substantially substituted alkylxanthine derivatives or their salts, by reaction of halogenoalcohilxanthines with amines, characterized in that 1-delta, 7-halogenoalkyl-3,7- or -1,3-dimethylxanthines are reacted with primary oxyalcohilamines, which in the radical alkyl may optionally be substituted by a phenyl group, at an elevated temperature.
