The asymmetric unit of title compound, C12H15BrN2O4S, contains two molecules (A and B), with slightly different conformations: the bromophenyl rings and the SO2 planes of the sulfonyl groups are oriented at dihedral angles of 50.2 (2) (molecule A) and 58.24 (7)° (molecule B), and the ethyl acetate groups make dihedral angles of 63.99 (19)° (A) and 65.35 (16)° (B) with their bromophenyl groups. In the crystal, both molecules exist as inversion dimers linked by pairs of N—H
O hydrogen bonds, which generate R22(14) loops. The dimers are linked by C—HO interactions.

In the title compound, C15H16N2O2S, the dihedral angle between the 4-methoxyaniline and 2-aminobenzenethiole fragments is 35.60 (9)°. A short intramolecular N—HS contact leads to an S(5) ring. In the crystal, molecules are consolidated in the form of polymeric chains along [010] as a result of N—HO hydrogen bonds, which generate R32(18) and R43(22) loops. The polymeric chains are interlinked through C—HO interaction and complete R22(8) ring motifs.
