چکیده
The title compound, C(19)H(22)N(4)O(3)S, comprises a thienopyridine moiety which is characteristic for anti-platelet agents of the clopidogrel class of compounds. In the crystal, inversion dimers are formed through pairs of C-H⋯O inter-actions. The benzene ring plane and the nitro plane are almost coplanar, with a dihedral angle of 0.83 (2)°. The piperazine ring adopts a chair conformation.
