Abstract :
Aryl carboxylic acid N -(4-oxo-4,5-dihydro-thiazol-2-yl)hydrazides (4a-g) were prepared from the reactions of 2-carbethioxymethylthio-2-thiazoline-4-one (2) with alkyl or aryl hydrazides (3a-g), in ethanol at room temperature. The reactions of compounds 4a-g with methyl and ethyl orthoformates afforded 2-aroyl-3-alkoxy-2,3-dihydrothiazolo[2,3-c][1,2,4]triazol-5(6H)-ones (5a-n). All newly synthesized compounds were fully characterized using Mass spectrometry, IR, 1H-NMR, 13C-NMR spectroscopy, and elemental analysis.
