N-Substituted (4H-thieno[3,2-b]pyrrol-5-yl)methanols were obtained by alkylation of methyl 4H-thieno[3,2-b]pyrrole-5-carboxylate followed by reduction with LiAlH4. These compounds on contact with Amberlyst 15 (H-form) in CH2Cl2 undergo self-condensation to produce bis(4H-thieno[3,2-b]-pyrrol-5-yl)methanes.
