Abstract
Treatment of ethyl 5-hydroxy-3,4-diphenylthieno[2,3-c]pyridazine-6-carboxylate (1a) with hydrazine hydrate in ethanol gave the carbohydrazide 2. Some derivatives of the latter compound have been synthesized. Also, 6-acetyl-3,4-diphenyl-5-hydroxythieno[2.3-c]pyridazine (1b) was subjected to some reactions to produce other new thienopyridazine derivatives.
