In the title compound, C27H28N2O 4, the pyrrolidine ring adopts a twist conformation. The plane of the indole ring is almost perpendicular to that of the pyrrolidine ring, making a dihedral angle of 88.50(6)°. The planes of the naphthyl ring system and the pyrrolidine ring are tilted by an angle of 55.86(5)°. The molecular conformation is stabilized by intramolecular O - H⋯O and O - H⋯N hydrogen bonds. © 2014 CrossMark.
