4‐(5‐Mercapto‐1,2,4‐triazolylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 3a , 4‐(5‐Methylmercapto‐1,2,4‐triazolylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 3b , 4‐(2‐Benzothiazolylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 3c and 4‐(4‐Methyl‐2‐benzothiazolylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐ones 3d are synthetized by condensation of corresponding heterocyclic amines 2(a–d) and 4‐Chlor‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 1 . under the reflux reaction conditions. Alkali hydrolysis of 3(a–d) afforded the 2‐hydroxy‐ω‐nitroacetophenone 4 . Antibacterial activity of products 3(a–d) are investigated and results are submitted for their antibacterial activities against Escherichia coli Staphylococcus aureus and, Clebsiella .
