Abstract: | Reaction of ethyl 2‐diazo‐4,5,6,7‐tetrahydrobenzob]thiophene‐3‐carboxylate 1 with 3‐iminobutyronitrile 2 gave the hydrazone derivative 3 . The reactivity of the latter product toward a variety of chemical reagents as well as the biological activity of the newly synthesized products were studied. © 2000 John Wiley & Sons, Inc.
