1,2,3-Triazoles and their benzoderivatives have attracted considerable attention because of their theoretical interest and synthetic value. They also find numerous applications in industry and agriculture due to their extensive biological activities and successful application as fluorescent whiteners, light stabilizers and optical brightening agents (Sanghvi, et al., 1990). Many 1,2,3-triazoles are found to be potent antimicrobial (Chen, et al., 2000; Sherement, et al., 2004), analgesic (Kreutzberger & Stratmann, 1980), anti- inflammatory, local anesthetic (Banu, et al., 1999), anticonvulsant (Peter & Roger, 2004), antineoplastic (Passannanti, et al., 1998), antimalarial (Jilino & Stevens, 1998) and antiviral agents (Safonova, et al., 2003). Some of them also exhibited antiproliferative (Manfredini, et al., 2000) and anticancer activity (Melo, et al., 2003). A good number of derivatives of 1,2,3-triazoles are used as DNA cleaving agents and potassium channel activators (Biagi, et al., 2004).

In the title molecule, C₁₅H₁₁F₃N₄O, Fig.1., the quinoline unit is nearly planar. The dihedral angle between the pyridine ring and the fused benzene ring is 2.45 (6)°. The triazole ring makes a dihedral angle of 63.7 (1)° and 64.7 (1)°, with that of pyridine and benzene rings respectively. The ethanone group is coplanar with the attached triazole ring, except the methyl H atoms. C—H···O, C—H···N and C—H···F hydrogen bonds are found in the crystal structure; see Fig.2 and hydrogen bond table. Furthermore, there is a short intermolecular C12···C12 contact which is caused by an intermolecular hydrogen bond H12 is involved in as well as by π-stacking effects.

Experimental top

4-Azido-8-trifluoromethyl quinoline (15 g, 0.06 mol) was treated with acetylacetone (6.4 g, 0.06 mol) in methanol (75 ml) and the mixture was cooled to 273 K. Sodium methoxide (3.5 g, 0.06 mol) was added under nitrogen atmosphere to the above mixture and then stirred at ambient temperature for 6–8 h. Progress of the reaction was monitored by TLC (ethylacetate:n-hexane: 2:3, v/v). The reaction mass was poured into ice cold water, precipitated solid was filtered and washed with water. The crude product was recrystallized from methanol. Yield 13.5 g (65%).

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
