The title compound, C19H22N4O3S, comprises a thienopyridine moiety which is characteristic for anti­platelet agents of the clopidogrel class of compounds. In the crystal, inversion dimers are formed through pairs of C—H⋯O inter­actions. 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.

Comment top

Clopidogrel is an oral, thienopyridine class antiplatelet agent used to inhibit blood clots in coronary artery disease, peripheral vascular disease, and cerebrovascular disease (Muller et al., 2003; Savi et al., 1994; Sharis et al., 1998). The crystal structure of the title compound (I), a derivative with thienopyridine, synthesised through the transformation of clopidogrel, is reported here.

The C14–C19 benzene ring plane and the nitro plane defined by O2/O3/N4 are almost coplanar, with a dihedral angle of 0.83° (Fig. 1). The piperazine ring shows a stable chair conformation. The bond angle in the ring ranges from 107.24–112.67°. The dihedrals formed between C10–C13 plane and C11/C12/N3 plane, C10–C13 plane and C10/C13/N2 plane are 43.32° and 55.40°, respectively. The packing is realised by C—H···O (Table 1) interactions leading to centrosymmetric dimers.

Experimental top

2-Chloro-1-(4-(4-nitrophenyl)piperazin-1-yl)ethanone 4 g (0.014 mol) and anhydrous K2CO3 7.7 g (0.056 mol) were dissolved in 40 ml toluene. The mixture was heated to 373 K. Then 2.2 g (0.015 mol) of 4,5,6,7-tetrahydrothieno[3,2-c] pyridine was added dropwise into the mixture, and stirred for 16 h under room temperature. K2CO3 was removed after filtration and the reaction solution was concentrated under reduced pressure to get yellow powder as a crude product. The powder was dissolved in a mixture of petroleum ether (20 ml) and acetone (4 ml) at 277 K, then white crystals were grown slowly.

Refinement top

All the H atoms were located on their parent atoms with C—H = 0.95 Å (aromatic CH) and 0.99 Å (CH2), Uiso = 1.2Ueq(C).

Special details top

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