In the title compound, C(18)H(20)N(2)O(3), the N-methyl-piperidone ring adopts a chair conformation. The pyrrolidine ring and the five-membered cyclo-pentane rings adopt envelope conformations. The five-membered ring of the ninhydrin system adopts an envelope conformation with the central C atom deviating by 0.217 (1)Å from the mean plane through the other atoms. The mol-ecular packing is characterized by inter-molecular C-H⋯O and intra-molecular C-H⋯O and O-H⋯N inter-actions.
