Synthesis of 6-[4-(allyl/phenyl)-5-thioxo-1,2,4-triazol-3-yl]pyrimidine-2, 4-diones and their reaction with electrophiles

Cyclization of 1-(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-6-yl)carbonyl-4-R- thiosemicarbazides in basic medium gave 6-(4-R-5-thioxo-1,2,4-triazol-3-yl) pyrimidine-2,4-diones (R = Allyl, Ph). Alkylation of the latter with iodomethane occurred at the sulphur
