Abstract: In the title molecule, C₁₃H₁₃NO, the dihedral angle between the benzene and pyrrole rings is 1.05 (5)°. The cycloheptene ring adopts a slightly distorted boat conformation. In the crystal structure, intermolecular N-HO hydrogen bonds form centrosymmetric dimers. A C-H interaction, involving the benzene ring, is also found in the structure.
