Alkylation of 1,2,4-triazine-6-thiones with 4-iodobutyne, followed by oxidation to the sulfoxide and intramolecular cycloaddition (at room temperature), gives 2,3-dihydrothieno[2,3-c]pyridines, which are readily dehydrated with acetic anhydride to thieno[2,3\_c]pyridines. The same series of reactio
