title: 2-Ethyl-6-(2-pyrid-yl)-5,6,6a,11b-tetra-hydro-7H-indeno[2,1-c]quinoline.
abstract: The title compound, C(23)H(22)N(2), was obtained using the three-component imino Diels-Alder reaction via a one-pot condensation between anilines, α-pyridine-carboxy-aldehyde and indene using BF(3)·OEt(2) as the catalyst. The mol-ecular structure reveals the cis-form as the unique diastereoisomer. The crystal structure comprises one-dimensional zigzag ribbons connected via N-H⋯N hydrogen bonds. C-H⋯π inter-actions also occur.
