In the title compound, C(29)H(34)N(2)O(2), the central piperidine ring adopts a half-chair conformation, whereas the terminal one adopts a chair conformation. The mean plane of the central piperidine ring [maximum deviation = 0.384 (2) Å] makes dihedral angles of 64.82 (13) and 17.55 (13)° with the benzene rings. In the crystal, mol-ecules are linked into a tape along the b axis via C-H⋯O inter...
