Abstract
Procedure for the preparation of new thiazolo [5,4-d] pyrimidines of the general formula I **(See formula)** wherein R1 signifies a hydrogen atom, a phenyl or lower alcohol radical, R2 and R3 which may be the same or different, mean piperazine or 1,4-diazacycloheptane groups, optionally substituted in position 4 by an acyl, carbamoyl, benzyl radical, lower alcohol or lower hydroxyalkyl, morpholino groups, hexahydro-1,4-oxoazepine, thiomorpholine, 1-oxide-thiomorpholine, 1,1-dioxide-thiomorpholine, hexahydro-1,4-thiazepine, 2-oxide-hexahydro-1,4 -thiazepine, 1,1-dioxide-hexahydro-1,4-thiazepine, alkanolamino, dialkanolamino, methoxyalkyl-alkanolamino, alcohol-alkaniolamino, cycloalkyl-alkaniolamino, alkanol-alkaniolamino or alcohol-diamine amino, where all the above-mentioned heterocyclic radicals can be in the skeleton carbonized by one or two lower alcohol radicals; as well as its salts with physiologically compatible organic or inorganic acids, characterized in that a compound of the general formula II is oxidized in a solvent **(See formula)** where R1 is as initially defined, one of the radicals R'2 or R'3 has the initially mentioned meanings for R2 or R3 and the other of the radicals R'2 or R'3 means a thiomorpholino or hexahydro radical -1,4-thiazepine optionally substituted by one or two lower alcohol radicals; and in case a compound of the general formula I with a free imino group is obtained according to the procedure, if desired this is subsequently acylated and/or transformed into a salt with a physiologically compatible organic or inorganic acid.
