Özet

In the title mol-ecule, C24H28N2O3, the cyclo-hexene ring is in a sofa conformation and the 1,4-dihydro-pyridine ring is in a slight boat conformation. In the indole ring system, the pyrrole and benzene rings form a dihedral angle of 2.63 (7)degrees. In the crystal, N-H center dot center dot center dot O hydrogen bonds connect the mol-ecules into C(6) chains parallel to the b axis and pairs of weak C-H center dot center dot center dot O hydrogen bonds link inversion-related chains into a ladder motif through R-2(2)(18) rings. A weak intra-molecular C-H center dot center dot center dot O hydrogen bond is also observed.
