The asymmetric unit of the title compound, C20H32N4O4S, contains one half-molecule; a twofold rotation axis passes through the thiophene ring. Intramolecular N—H⋯O hydrogen bonding results in the formation of a nearly planar six-membered ring, which is oriented at a dihedral angle of 4.60 (3)° with respect to the thiophene ring. In the crystal structure, intermolecular C—H⋯N and C—H⋯O hydrogen bonds link the molecules. [ABSTRACT FROM AUTHOR]
