1-Ethoxycarbonyl-2-methylthio-1,4,5,6-tetrahydropyrimidine (1) reacting with acylhydrazines, affords 2-acyl derivatives of 3-oxo-2,3,5,6,7,8-hexahydro-s-triazolopyrimidine (2) or 2-acylhydrazine derivatives of 1.The acylation of 2 and its 2-phenyl derivative 3 with isothiocyanates give corresponding 3-oxo-2,3,5,6,7,8-hexahydro-s-triazolopyrimidine 11a, b, 13a, c and 14.
