The reaction of 1-benzothiophen-3(2H)-one hydrazone with various ketones under different conditions has been studied and a convenient method has been proposed for the synthesis of thienopyrrole derivatives. The method is applicable to the preparation of 1H- and 3H-benzothienopyrroles with a range of substituents.
