In the title compound, C16H14BrN3O2S, the atoms of the 1,3-thiazolidine group, except for the N and the C atoms attached to the bromobenzene ring, are disordered over two sets of sites with occupancies of 0.605 (13) and 0.395 (13). The benzene and pyridine rings make a dihedral angle of 86.2 (2)°. In the crystal, molecules are linked by intermolecular N—H⋯N and C—H⋯O hydrogen bonds, forming a three-dimensional network. Furthermore, there is a π–π stacking interaction [centroid–centroid distance = 3.758 (2) Å] between the pyridine and benzene rings.

N'-(4-bromobenzylidine)pyridine-3-carbohydrazide (0.01 mol) was reacted with 0.028 mol of 2-mercaptopropanoic acid in anhydrous benzene for 7 h using a Dean-Stark trap. Excess benzene was removed under reduced pressure. The residue was triturated with saturated sodium bicarbonate solution. The separated solid was filtered, washed with water and crystallized from methanol to yield white crystalline N-[5-methyl-2-(4-bromophenyl)-4-oxo-1,3-thiazolidin-3-yl]pyridine-3-carboxamide.

The C-bound H atoms were geometrically placed (C—H = 0.93–0.98 Å) and refined as riding with Uiso(H) = 1.2 or 1.5Ueq(C). The N-bound H atom was located from the Fourier synthesis and restrained to 0.86 (2) Å, and refined with Uiso(H) = 1.2Ueq(N). The 1,3-thiazolidine group, except for the N1 and C7 atoms, is disordered over two sites with site occupancies of 0.605 (13) and 0.395 (13). In the last cycles of the

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 e.s.d.'s 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. |

Pyridine-3-carboxamides have gained attention because of their diverse pharmacological properties such as anti-inflammatory (Abdel-Alim et al., 2005), anticancer (Girgis et al. 2006), cytoprotective (Slominska et al., 2008), and anxiolytic (Spanka et al., 2010) activities. 4-Thiazolidinone derivatives have antineoplastic (Vigorita et al., 1992), HIV-1 RT inhibitory (Barreca et al., 2003; Rao et al., 2004), hypolipidemic (Jacop & Kutty, 2004), and anti-inflammatory (Kalia et al., 2007) activities. In an effort to evaluate bioactive molecules bearing both 4-thiazolidinone and pyridine-3-carboxamide scaffolds together, we synthesized N-(thiazolidin-3-yl)pyridine-3-carboxamide derivatives to examine their antiviral and anticancer properties.
In the 1,3-thiazolidine group of the title molecule (Fig. 1), all except the N1 and C7 atoms are disordered. The dihedral angle between the ring planes (S1A/N1/C7/C8A/C9A and S1B/N1/C7/C8B/C9B) formed by the major and minor disorder components is 18.5 (8) °.
The benzene (C1–C6) and pyridine (N3/C12–C16) rings make a dihedral angle of 86.21 (19) ° with each other. The N1—N2—C11—C12, N1—N2—C11—O2, N2—C11—C12—C13 and O2—C11—C12—C13 torsion angles are 180.0 (3), 1.2 (6), 172.2 (3) and -9.0 (6)°, respectively.
The molecular structure has two weak intramolecular C—H···N interactions (Table 1), generating S(5) ring motifs, and the crystal structure is stabilized by intermolecular N—H···N and C—H···O hydrogen bonds (Table 1 and Fig. 2). In addition, a π-π stacking interaction is observed [Cg3···Cg4(1/4 + y, 1/4 - x, 1/4 + z) = 3.758 (2) Å, where Cg3 and Cg4 are the centroids of the pyridine N3/C12–C16 and benzene C1–C6 rings, respectively].
