In the title compound, C(15)H(13)NO(2), all atoms of the carbazole group are coplanar (r.m.s. deviation = 0.005 Å), and the dihedral angle between this plane and C-O-C plane of oxane group is 57.1 (4)°. The crystal packing is stabilized by an N-H⋯O hydrogen bond, resulting in infinite supra-molecular chains along [001].
