A new, effective method has been developed for the synthesis of functionalized thieno[2,3-b]pyridines by multicomponent condensation reactions of aromatic and heteroaromatic aldehydes, cyanothioacetamide, acetoacetanilides, and alkylating agents containing activated methylene groups. The structures of 3-amino-2-benzoyl-4-(furan-2-yl)-6-methyl-N-phenylthieno[2,3-b]pyridine-5-carboxamide, 3-amino-N2
