The title compound, C24H29N3O5S, is a chiral mol­ecule which crystallizes in a centrosymmetric space group as a racemate. The thia­zolidine ring forms the dihedral angles of 29.22 (12) and 67.79 (10)° with the benzene and pyridine rings, respectively. The benzene and pyridine rings are tilted by dihedral angle of 67.18 (9)°. In the crystal, inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional network.

Comment top

The title compound is a type of thiazolidinedione material, which was synthesised from rosiglitazone and tert-butyl chloroacetate. In this paper, we report the synthesis and crystal structure of the title compound.

The title compound is chiral with a stereogenic centre C16 of the thiazolidine ring. However, it crystallises in the centrosymmetric space group as a racemate. The thiazolidine ring forms the dihedral angles of 29.22 (12) ° and 67.79 (10) ° with the benzene ring and pyridine ring, respectively. The benzene ring and the pyridine ring are tilted by 67.18 (9) ° (Fig. 1). In the crystal, intermolecular C—H···O hydrogen bonds link the molecules into a two-dimensional network (Table 1 and Fig. 2).

Experimental top

A solution of C2H5ONa (1.00 g) in anhydrous ethanol (50 mL) was added slowly to a solution of rosiglitazone (5 g) in anhydrous ethanol (125 mL) at room temperature and the mixture was stirred for 12 h. After completion of the reaction, the mixture was filtered and the white powder was dried at 323 K to afford sodium rosiglitazone (5.15 g). tert-Butyl chloroacetate (0.80 g) was added to a suspension of sodium rosiglitazone (1.51 g) in acetonitrile (70 mL) and the mixture was refluxed for 11 h. After completion of the reaction, the warm suspension was filtered and the filtrates were concentrated under vacuum. Single crystals were obtained by recrystallisation from EtOH : EtOAc (1 : 2) at room temperature.

Refinement top

All H atoms, were positioned geometrically with C—H distances ranging from 0.93 Å to 0.97Å and refined as riding on their parent atoms with Uiso(H) = 1.5Ueq(C)

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) 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.
