Abstract

In the title compound, C(14)H(16)N(2)O(4)S, the eth-oxy-carbonyl 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 mol-ecules are linked into dimers by pairs of N-H⋯O hydrogen bonds, forming rings of R(2) (2)(10) graph-set motif. The dimers are further connected by weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming layers parallel to the bc plane.
