The title compound, C15H19NO3S, has cis stereochemistry at the ring junction, resulting from an exo intramolecular 1,3-dipolar cycloaddition. It crystallizes as a racemate. The tetrahydrothieno ring has an S-envelope form and the pyrrole ring adopts a half-chair conformation. The amino H atom is shared in a bifurcated intramolecular hydrogen bond between the bare O atoms of the carboxylate and methoxy groups. Cohesion of the structure is achieved through weak intermolecular interactions only.
