Abstract: The title compound, C₁₈H₂₁NO₃, consists of a carbazole skeleton with carboxyethyl and ethyl groups at positions 2 and 3, respectively. The heterocyclic ring and the benzene ring fused to it are nearly planar, while the cyclohexenone ring adopts a distorted sofa conformation. Molecules are linked in pairs about inversion centers by N-HO hydrogen bonds [NO = 2.831  (3)  Å and N-HO = 158  (3)°].
