To the solution of benzimidazole-2-thione (1,35 g, 9 mmoles) and dichloroethyl amine hydrochloride (2,41 g, 13.5 mmoles) in dimethylformamide (80 ml) were added potassium carbonate (4,14 g, 30 mmoles) and tetra-n-butylammonium bromide (0,10 g, 0,3 mmoles). The resulting mixture was refluxed for 4 h. After filtering the solvent was removed and the residue was purified by

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. |

The synthesis of new oxindole derivatives having an oxazolindin-2-one unit has been detailed in recent reports (Al Subari et al., 2010a,b; Ahoya et al., 2010; Ballo et al.,2010).
In the new oxazolidin-2-one, C12H13N3O2S, the dihedral angle between the 1H-benzimidazole ring and the 1,3-oxazolidin-2-one mean plane is: 69.85 (13)° (Fig.1). The oxazolidin ring is not planar but display envelope conformation on C14 with puckering parameters Q(2) = 0.258 (3) Å and φ(2) = 63.3 (7) ° (Cremer & Pople, 1975).
In the crystal structure, the molecules are linked by intermolecular N—H···N hydrogen bonds forming a chain parallel to the b axis (Table 1, Fig. 2).
