In the title molecule, C18H15NO2, the carbazole unit is not planar [maximum deviation from mean plane = 0.236 (2) Å]. The pyrrole ring makes dihedral angles of 1.21 (10) and 16.74 (12)° with the benzene and the furan rings, respectively. The cyclohexene ring adopts a half-chair conformation. In the crystal, inversion dimers linked by pairs of N—H...O hydrogen bonds generate R22(10) loops.
