4‐(3‐Hydroxy‐2‐pyridinylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 4a , 4‐(3,5‐Dichlor‐2‐pyridinylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 4b , 4‐(4‐Methyl‐2‐pyrimidinylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 4c and 4‐(4‐Hydroxy‐6‐methyl‐2‐pyrimidinylamino)‐3‐nitro‐2H‐[1]‐benzopyran‐2‐ones 4d are synthetized by condensation of 4‐Chlor‐3‐nitro‐2H‐[1]‐benzopyran‐2‐one 2 and corresponding heteroarylamines 3(a–d) under the reflux reaction conditions. Alkali hydrolysis of 4(a–d) afforded the 2‐hydroxy‐?‐nitroacetophenone 5 . Antibacterial activity of products 4(a–d) are investigated and results are submitted for their activities against Staphylococcus aureus, Clebsiella and Escherichia coli.
