When 7-aroylalkyl-8-bromo-3-methyl- and -1,3-dimethylxanthines are boiled with an excess of thioglycolic acid, a reductive dehalogenation takes place, while reaction with an equimolar amount of thioglycolic acid in DMFA leads to 7-aroylalkyl-3-methyl- and -1,3-dimethylxanthinyl-8-thioacetic acids.Cyclization of the latter with acetic anhydride in the presence of anhydrous sodium acetate results in the formation of 3-aryl-1,4-dihydro-9-methyl- and -7,9-dimethylthiazino<3,2-f>xanthine.
