(Received 17 December 2009; accepted 15 January 2010; online 23 January 2010)

In the title compound, C10H12N2OS, the asymmetric unit consists of two independent mol­ecules. In the crystal structure, mol­ecules form R44(28) centrosymmetric tetra­mers via O—H⋯N hydrogen bonds. These tetra­mers are stacked along the c axis via C—H⋯O hydrogen bonds. C—H⋯π and π–π inter­actions are also present; in the latter, the centroid–centroid distances are 4.075 (1) and 3.719 (1) Å.

Comment top

Numerous compounds having benzimidazole ring systems possess versatile pharmacological activities such as antiviral, anthelmintic, spasmolytic, antihypertensive and vasodilator (Akkurt et al., 2006). It has also been reported that many benzimidazole derivatives have antimicrobial and antifungal activities (Küçükbay et al., 2003, 2004, Puratchikody et al., 2008). Therefore, the synthesis of new benzimidazole derivatives is of considerable interest. In order to explore new benzimidazole properties, the title compound has been synthesized and its crystal structure determined.

The two independent molecules in the asymmetric unit of the title compound and the atomic labeling scheme are shown in Fig.1. In this structure, the nine-membered benzimidazole ring systems (N1A/C3A/N2A/C6A/C7A/C8A/C9A/C10A/C5A, N1B/C3B/N2B/C6B/C7B/C8B/C9B/C10B/C5B) of both independent molecules are essentially planar, the maximum deviation from planarity being, respectively, 0.016 (2) Å for atom C8A and 0.078 (16) Å for atom C3B. These two ring systems make a dihedral angle of 73.95 (6)°.

In the crystal structure, we observe the formation of R44(28) centrosymmetric tetramers (Bernstein et al., 1995) via O—H···N hydrogen bonds. The tetramers are linked by two symmetric C—H···O hydrogen bonds to form a zigzag infinite chain along the c axis. The supramolecular aggregation is completed by the presence of C—H···π interactions (Table 1) and π–π stacking between two parallel imidazole rings. The centroid···centroid distance of those rings, Cg1···Cg1(1 - x,1 - y,1 - z) and Cg4···Cg4(-x,2 - y,-z) are 4.075 (1) Å and 3.719 (1) Å, respectively (Fig.3).

Experimental top

2-Chloroethanol (1.6 ml, 24.4 mmol) and potasium carbonate (1.68 g, 12.2 mmol) were added to 2-methylsulfanyl-1H-benzimidazole (1 g, 6.1 mmol) in dimethyl sulfoxide (DMSO) (5 ml). The reaction mixture was successively agitated for 30 min at room temperature and at 323 K for 24 h. 50 ml of water was then added to the reaction mixture, and the products were extracted with dichloromethane (3 × 50 ml). The combined organic extracts were washed with brine (10 g of sodium chloride in 100 ml of water), dried (Na2SO4) and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (elution: hexane/ethyl acetate (70:30, v/v)) and the title compound resulted as a brown powder (0.77 g, 61%) with a melting point of 409 K. The brown powder was dissolved in ethanol/hexane (3:1, v/v) and, after four days, brown crystals suitable for single-crystal X-ray diffraction analysis were obtained.

Refinement top

The H atoms bonded to O1A and O1B were located in a difference Fourier map; their positional parameters and Uiso were refined freely. Other H atoms were placed at calculated positions, with C—H = 0.95 Å and refined using a riding model, with Uiso(H) constrained to be 1.2Ueq(C).

Experimental. 1H NMR (DMSO-d6, 300 MHz, p.p.m.) δ: 2.71 (s, 3H, CH3); 3.68–3.74 (m 2H, CH2O, JCH2—CH2 = 5.7 Hz and JCH2—OH = 5.4 Hz); 4.17 (t, 2H, CH2N, JCH2—CH2 = 5.7 Hz); 5.00 (t, 1H, OH, JCH2—OH = 5.4 Hz); 7.13–7.17 and 7.46–7.55 (m, 4H, C6H4). 13C NMR (DMSO-d6, 300 MHz, p.p.m.) δ: 14.35 (CH3); 46.25 (CH2N); 59.14 (CH2O); 109.75, 117.31, 121.14, 121.21, 136.75, 142.92 (C6H5); 152.48 (C═N).

Refinement. The 15 reflections 1 0 0; -1 1 0; 0 1 0; 1 1 0; -1 - 1 1; 0 - 1 1; 1 - 1 1; -1 0 1; 0 0 1; 1 0 1; -1 1 1; 0 1 1; 1 1 1; 0 0 2; 0 1 2 have been measured with too low intensities. It might be caused by some systematical error, probably by shielding by a beam stop of these diffractions. They were not used in the refinement.
