2-Hy­droxy-5-[(E)-2-methyl­benzyl­idene]-8-(2-methyl­phen­yl)-9-phenyl-3,10-diaza­hexa­cyclo­[10.7.1.1^3,7.0^2,11.0^7,11.0^16,20]henicosa-1(20),12,14,16,18-pentaen-6-one

In the title compound, C₄₀H₃₄N₂O₂, the central piperidine ring adopts a half-chair conformation and the fused pyrrolidine rings adopt twisted envelope (with the C atom bearing the methylphenyl ring as the flap atom) and envelope (with the C atom bound to the N atom, common to the pyridinone and pyrrolidine rings being the flap atom) conformations. The mol­ecular structure features weak intra­molecular N—H...O and C—H...O inter­actions. In the crystal, O—H...O hydrogen bonds generate a C(7) chain along the b-axis direction. C—H...O inter­actions also occur.
