REACTION OF CYCLIC THIOUREAS WITH CHLOROACYLPIPERAZINES

S-Alkylation products are formed in the reaction of tetrahydropyrimidine-2-thione and hexahydro-1,3-diazepine-2-thione with chloroacylpiperazines in dimethylformamide at room temperature; dihydrothiazolopyrimidine and tetrahydrothiazolo-diazepine systems are obtained in refluxing ethanol.It is shown that the S-alkyl derivatives are very readily converted to condensed systems.
