R. Iqbal et al., SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF 2,4-DIHYDRO-4-BENZYL-5-(ISOMERIC PYRIDYL)-3H-1,2,4-TRIAZOLE-3-THIONES, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 37(5), 1998, pp. 506-509
Intramolecular cyclization of the: three isomeric 1,4-disubstituted th
iosemicarbazides 3a-c in aqueous sodium hydroxide affords 2,4-dihydro-
4-(benzyl)-5-(isomeric pyridyl)-3H-1,2,4-triazole-3-thiones 4a-c. The
antibacterial activity of these compounds has been determined against
seventeen, gram positive and gram negative microorganisms.
