Condensation of 5-cyano-2-hydrazino-3-N-methyl-6-phenyl/p-chlorophenyl-3, 4- dihydropyrimidin-4-one (3a and 3b) with 2, 4-bisalkyl/arylamino-6-chloro-s-triazine (4) gave the corresponding 2, 4-bisalkyl/arylamino-6-[5′-cyano-3′-N-methyl]-6′-phenyl/p- chlorophenyl-3′, 4′-dihydropyrimidin-4′-one-2′-yl-hydrazino-s-triazines (5a–n and 6a– n). The compounds 4 have been prepared by the condensation of cyanuric chloride and ...
