Abstract: In the title compound, C₁₁H₁₅NO₃, the molecules are joined into dimers by a pair of strong hydrogen bonds between the pyrrole N atom and the carbonyl O atom of the carboxylate substituent [NO 2.861 (2) Å and N-HO 168 (2)°]. A single C-H intermolecular interaction is observed, with an H distance of 3.04 Å, linking the dimers together.
