4-Bromo-3-oxo-2-phenylhydrazono-butyronitrile (II) reacted with thioamides to afford the thiazole derivatives III and VI. Compound II reacted with nucleophilic reagents to afford XIIIa and XIIIb. The reactivity of XIIIa with some chemical reagents was studied to afford pyridazine, thiazole, 1,2,4-triazine derivatives.
