Abstract: In the title compound, C21H20N2O, the piperidine ring adopts a chair conformation while the pyran ring adopts a screw-boat conformation. The piperidine ring forms dihedral angles of 65.75 (3) and 67.79 (5)° with the chroman and methyl-substituted benzene rings, respectively. The crystal structure features weak C-H...[pi] and [pi]-[pi] [centroid-centroid distance = 3.8098 (8) Å] interactions.
