(Received 4 December 2009; accepted 7 December 2009; online 12 December 2009)

In the mol­ecule of the title compound, C15H13Cl2N3O2, the triazole ring is oriented at dihedral angles of 2.54 (13) and 44.43 (12)°, respectively with respect to the furan and dichloro­benzene rings. The dihedral angle between the dichloro­benzene and furan rings is 46.75 (12)°. In the crystal structure, inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into centrosymmetric dimers and ππ contacts between dichloro­benzene rings [centroid–centroid distance = 3.583 (2) Å] may further stabilize the structure. Inter­molecular C—H⋯π contacts between the triazole and furan rings also occur.

Comment top

In recent years, among antifungal agents, azole derivatives still have an important place in the class of systemic antifungal drugs. Some ether structures containing 1H-imidazole ring like micozanole, ecozanole and sulconazole have been synthesized and developed for clinical uses as antifungal agents (Godefroi et al., 1969). The crystal structures of these ether derivatives like miconazole (Peeters et al., 1979), econazole (Freer et al., 1986) have been reported previously. Also, antifungal activity of aromatic ethers possessing 1H-1,2,4-triazole ring have been reported (Wahbi et al., 1995). Itraconazole (Peeters et al., 1996) and fluconazole (Caira et al., 2004) are 1H-1,2,4-triazole ring containing azole derivatives. 1,2,4-Triazoles are biologically interesting molecules and their chemistry is receiving considerable attention due to antihypertensive, antifungal and antibacterial properties (Paulvannan et al., 2001). Ether structures possessing 1H-benzimidazole ring have been reported to show antibacterial activity more than antifungal activity (Özel Güven et al., 2007a,b). The crystal structures of 1H-benzimidazole ring containing ether derivatives (Özel Güven et al., 2008a,b,c,d) and also,1H-1,2,4-triazole ring containing ether derivatives have been reported recently (Özel Güven et al., 2008e,f; Özel Güven et al., 2009). Now, we report herein the crystal structure of 2,6-dichloro- derivative of 1H-1,2,4-triazole and furyl rings containing ether structure.

In the molecule of the title compound (Fig. 1) the bond lengths and angles are generally within normal ranges. The planar triazole ring is oriented with respect to the furan and dichlorobenzene rings at dihedral angles of 2.54 (13)° and 44.43 (12)°, respectively. Atoms C3, C4 and C9 are -0.064 (3), 0.039 (3) and -0.073 (3) Å away from the planes of the triazole, furan and dichlorobenzene, respectively. So, they are nearly coplanar with the adjacent rings. The dichlorobenzene ring is oriented with respect to the furan ring at a dihedral angle of 46.75 (12)°. An intramolecular C—H···Cl hydrogen bond (Table 1) results in the formation of a five-membered ring (Cl2/H9B/C9/C10/C15) adopting envelope conformation with H9B atom displaced by 0.210 (1) Å from the plane of the other ring atoms.

In the crystal structure, intermolecular C-H···O hydrogen bonds (Table 1) link the molecules into centrosymmetric dimers (Fig. 2), in which they may be effective in the stabilization of the structure. The ππ contact between the dichlorobenzene rings, Cg3—Cg3i [symmetry code: (i) -x, -y, 1 - z, where Cg3 is centroid of the ring (C10-C15)] may further stabilize the structure, with centroid-centroid distance of 3.583 (2) Å. Intermolecular C—H···π interactions (Table 1) are also observed between the triazole and furan rings.

Experimental top

The title compound was synthesized by the reaction of 1-(furan-2-yl)-2-(1H-1,2,4-triazol-1-yl)ethanol (unpublished results) with NaH and appropriate benzyl halide. To a solution of alcohol (500 mg, 2.791 mmol) in DMF (4 ml) was added NaH (112 mg, 2.791 mmol) in small fractions. The appropriate benzyl halide (669 mg, 2.791 mmol) was added dropwise. The mixture was stirred at room temperature for 3 h, and excess hydride was decomposed with methyl alcohol (5 ml). After evaporation to dryness under reduced pressure, the crude residue was suspended with water and extracted with methylene chloride. The organic layer was dried over anhydrous sodium sulfate and then evaporated to dryness. The crude residue was purified by chromatography on a silica-gel column using chloroform as eluent. Crystals suitable for X-ray analysis were obtained by the recrystallization of the ether from isopropanol solution (yield; 500 mg, 53%).

H atoms were positioned geometrically, with C–H = 0.93, 0.98 and 0.97 Å for aromatic, methine and methylene H, respectively, and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C).

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.
