Abstract: The title molecule, C₁₄H₁₃NO₂, is almost flat with a dihedral angle of 8.0 (1)° between the pyrrole and benzene rings. The central C₃O ketone unit has an s-cis conformation and is also coplanar with a torsion angle of -0.6 (3) °. An intramolecular C-HO hydrogen bond generates an S(5) ring motif. In addition, the methoxy group is coplanar with the attached benzene ring. In the crystal structure, neighboring molecules are paired through N-HO hydrogen bonds into centrosymmetric dimers with an R²₂(10) motif.
