Abstract

In the title compound, C14H16N2O4S, the eth­oxy­carbonyl group is nearly planar, with an r.m.s. deviation of 0.0067 Å, and is almost coplanar with the pyrrole ring [dihedral angle = 5.81 (15)°], whereas it is inclined at a dihedral angle of 61.90 (13)° to the phenyl ring. The dihedral angle between the pyrrole and phenyl rings is 56.15 (13)°. In the crystal, centrosymmetrically related mol­ecules are linked into dimers by pairs of N—H⋯O hydrogen bonds, forming rings of R22(10) graph-set motif. The dimers are further connected by weak inter­molecular C—H⋯O hydrogen bonds and C—H⋯π inter­actions, forming layers parallel to the bc plane.
