An effective method for the synthesis of N-ethyl-2,1,3-benzoselenadiazolamines 11 and 15 has been described. ModifiedGould-Jacobsreaction of N-ethylbenzoselenadiazol-4-amine 15 provided 9-ethylselenadiazoloquinolone derivatives 2 and 19 in high yields. Acid-promoted ring closure of enamine 18c unexpectedly afforded completely deacetylated product - 9- ethylselenadiazoloquinolone 2. Identical product
