The title compound, C18H21NO3, was obtained via a double Mannich condensation reaction of 6-methyl­tetra­hydro­isobenzofuran-1,7(3H,7aH)-dione with formaldehyde and benzyl­amine. The mol­ecule contains three fused rings of which the cyclo­hexa­none and piperidine rings adopt chair conformations and the furan­one ring assumes an envelope conformation. An inter­molecular C—H⋯π inter­action is present in the crystal structure
