Abstract

It has been established that the interaction  of  N1-(2-hydroxyphenylmethylthieno[2,3-b]pyrid-3-yl)arylamides with hydrazine hydrate leads to thieno[2,3-b]pyridine-2,3-diamines.  It was shown that the reaction of the latter with acetylacetone and acetoacetic ester  occurs regioselectively at the amino group in position 3 of the thiophene ring.
