As a part of ongoing studies in developing new potent antioxidant agents, N‐[4‐(aminosulfonyl)phenyl]‐2‐cyanoacetamide (3) was utilized as key intermediate for the synthesis of some new thiophene, chromene, and pyrazolotriazine pyridinederivatives. The structures of the newly synthesized compounds were confirmed by elemental analysis, IR, 1H‐NMR, and mass spectral data. Representative compounds of
