Abstract: In the title compound, C₁₇H₁₇N₃O₃S, key bond lengths are N-N 1.408  (2) and N-S 1.7023  (15)  Å. The relative orientation of the two ring systems is defined by the torsion angles between them, namely C-N-N-S 94.99  (15), N-N-S-C 123.90  (12) and N-S-C-C 107.86  (15)°. The molecules are linked in inversion-symmetric pairs by classical hydrogen bonds N-HO=C. All four CH₂ groups of the non-aromatic ring are disordered over two positions, corresponding to two alternative conformations.
