In the title compound, C29H29Cl2N3O2S, the phenyl ring is disordered over two orientations with occupancies of 0.55 (3) and 0.45 (3). The molecular packing in the crystal is stabilized by intermolecular N—H⋯O interactions, linking the molecules into infinite chains along the c axis. In addition, there are weak C—H⋯S and C—H⋯π interactions.

A mixture of 2-[2-(2,6-dichloroanilino)phenyl]-N'-(4-phenylcyclohexylidene)acetohydrazide (0.0025 mol) and 2-mercaptopropionic acid (2.5 ml) was refluxed in dry benzene (20 ml) using a Dean-Stark water separator for 6 h. The reaction mixture thus obtained was concentrated under vacuum and neutralized by addition of saturated NaHCO3 solution until CO2 evolution ceased. After refrigeration overnight, the precipitate was filtered, dried and purified by recrystallization from EtOH. Yield, 56.1 %, m.p. 492.7-494.3 K. UV (EtOH) λmax.= 279.6, 205.4 nm.

All hydrogen atoms except those of the disordered phenyl ring were located in a difference map. They were refined using a riding model with N—H = 0.86 Å and C—H = 0.93 - 0.98 Å, and with Uiso(H) = 1.2Ueq(C,N) or 1.5Ueq(Cmethyl). The phenyl ring of the molecule shows a positional disorder over two sites with refined occupancies of 0.55 (3) and 0.45 (3).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

Diclofenac, [2-(2,6-dichloroanilino)phenyl]acetic acid, is being used for its antiinflammatory activity for over 30 years and is a tolerable drug when compared with other NSAIDs. Still, its chronic use may elicit appreciable GI irritation, bleeding and ulceration due to its free –COOH group. Chemical modifications on the molecule have been made both to improve the safety profile and also to obtain derivatives with antimicrobial, antioxidant and anticancer properties by derivatization of the carboxylate function (Bandarage et al., 2000; Amir & Shikha, 2004; Galanakis et al., 2004; Sriram et al., 2006; Bhandari et al., 2008; Wittine et al., 2009). Following the same strategy, we prepared the title molecule bearing a spirothiazolidinone moiety to investigate its antimicrobial potential.
The phenyl ring of the title molecule (Fig. 1) is disordered over two orientations with occupancies of 0.55 (3) and 0.45 (3). The dihedral angle between the planes of the disorder phenyl rings (C24/C25A–C29A and C24/C25B–C29B) is 15.8 (9)°. The two benzene rings (C1–C6 and C7–C12) form dihedral angles of 25.2 (5), 26.6 (8)° and 67.7 (5), 83.4 (8)°, respectively, with these disorder phenyl rings.
Intermolecular N—H···O interactions link the molecules into infinite chains stretching along the c axis of the crystal (Fig. 2 and Table 1). In the crystal structure, weak C—H···π interactions occur between the (C17A)H17A atom of the methyl group and the C7–C12 benzene ring (Table 1).
