%X In the title molecule, C24H28N2O3, the cyclohexene ring is in a sofa conformation and the 1,4-dihydropyridine 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)¡ã. In the crystal, N¡ªH...O hydrogen bonds connect the molecules into C(6) chains parallel to the b axis and pairs of weak C¡ªH...O hydrogen bonds link inversion-related chains into a ladder motif through R22(18) rings. A weak intramolecular C¡ªH...O hydrogen bond is also observed.
