The reaction of 2-isonicotinoyl-N-arylhydrazinecarbothioamide (2a-c) with chloroacetic acid in presence of anhydrous sodium acetate in absolute ethanol yields, in each case, a single product. The single crystal X-ray analysis confirmed the structure of these products as N-(4-aryl)-5-(pyridine-4-yl)-1,3,4-oxadiazol-2-amines (4a-c).
