AMINOAZOLES IN HETEROCYCLIC SYNTHESIS - SYNTHESIS OF SOME NEW BENZIMIDAZOLO, TRIAZOLO, TETRAZOLO, PYRAZOLO, THIADIAZOLO, PYRIMIDO AND PYRIDINOQUINAZOLINONES

Some new condensed heterocycles were synthesized via condensation of , 4-dicarboxanilide-5-hydroxy-5-methylcyclohexanone with aminoazoles, na mely: 2-aminobenzimidazole, 3-amino-1,2,4-triazole, 5-aminotetrazole m onohydrate, 5-amino-3-phenylpyrazole, 4-(p-chlorophenylazo)-3,5-diamin opyrazole, 3-amino-5-methyl (or ethyl)thiadiazole, 2-amino-4,6-dihydro xypyrimidine and 2-amino-3-hydroxypyridine. Structures of the synthesi zed compounds are confirmed by both analytical and spectral data.
