Abstract: In the title compound, C18H23NO3, the cyclo­hexane ring has a chair conformation. The oxirane plane (OCC) makes a dihedral angle of 76.15 (13)° with that of the pyrrolidine ring to which it is fused. The mean plane of the cyclo­hexane ring and the benzene ring are almost normal to the pyrrolidine ring, with dihedral angles of 88.47 (8) and 77.85 (8)°, respectively. In the crystal, mol­ecules are linked via pairs of N-H...O hydrogen bonds, forming inversion dimers. These dimers are linked via pairs of C-H...O hydrogen bonds, forming chains along the a-axis direction.
