In the title molecule, C24H28N2O 3, 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 14;(7)°. In the crystal, N - HO hydrogen bonds connect the molecules into C(6) chains parallel to the b axis and pairs of weak C - HO hydrogen bonds link inversion-related chains into a ladder motif through R 2 2(18) rings. A weak intramolecular C - HO hydrogen bond is also observed.
