STRUCTURAL NMR ANALYSIS OF TRIAZOLIC COMPOUNDS DERIVED FROM ISONICOTINIC ACID
Abstract:
The present article is aimed towards the structural NMR analysis of 4H-4-amino-3-mercapto-5-(4-pyridil)-1,2,4-triazole (3) and its product of alkylation (via sodium salt) with ethyl chloroacetate in absolute ethanol. 4H-4-amino-3-mercapto-5-(4-pyridil)-1,2,4-triazole and 4H-4-amino-5-ethoxycarbonyl-methylsulfanyl-3-(4-pyridil)-1,2,4-triazole (4) were characterized by IR, 1H-NMR, 13C-NMR spectroscopy and structures were elucidated by 2D-1H-13C-HMBC spectroscopy.
