A series of new compounds 5a～5e, 6a～6e, 7a～7e and 8a～8e were synthesized though condensation reaction of 3-formylchromones 4a～4d with S-{[4-aryl-5-(pyrid-4-yl)]-1,2,4-triazol-3-yl}- mercaptoacetylhydrazine (3a～3e) which were obtained by esterification and hydrazinoly-sis from 3-mercapto-4-aryl-5-(pyrid-4-yl)-1,2,4-triazoles (2a～2e) cyclized from N-aryl-2-[(pyrid-4-yl)-carbonyl] thiosemicarbazide (1a～1e) in NaOH solution. Their structures were established by ele-mental analysis, IR, 1H NMR and MS spectra.

Key words: mercaptoacetamide, 1,2,4-triazole, 3-formylchromone
