The synthesis of (I) was carried out simply by heating equimolar amounts of 3-{1-[(3-fluoro-4-phenyl)phenyl]ethyl}-5-mercapto-1,2,4-triazole, chloroacetic acid and 2-fluorobenzaldehyde dissolved in acetic acid and acetic anhydride in the presence of anhydrous sodium acetate. The starting compound, 3-{1-[(3-fluoro-4-phenyl)phenyl]ethyl}-5-mercapto-1,2,4-triazole, was prepared by employing the previously reported procedure (Tozkoparan et al., 2000; Berk et al., 2001). Compound (I) was crystallized from acetone/su (su is? Ratio?) (yield 67.8%, m.p. 432–433 K). Spectroscopic analysis: IR (ν, cm−1): 3087, 3032 (aromatic C—H), 2970, 2932 (aliphatic C—H), 1744 (lactam C═O), 1616 (C═N); 1H NMR (CDCl3, δ, p.p.m.): 1.75 (d, 3H,CH3), 4.30 (q, 1H, CH), 7.10–7.60 (m, 12H, aromatic H), 8.30 (s, 1H, CH).
H atoms were located geometrically and refined using a riding model, fixing the aromatic C—H distance at 0.93 Å, the C—H2 distance at 0.97 Å and the C—H3 distance at 0.96 Å. The intensity data collected for (I) were generally weak, so the least-squares goodness-of-fit parameter lies outside the range (goodness-of-fit given 0.627). 1421 Friedel-related reflections were merged in the final refinement because of the meaninglessness of the absolute structure parameter value.

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. |

Since 6-benzylidenethiazolo[3,2-b]-1,2,4-triazole-5(6H)-one is structurally related to 5-(3,5-di-tert-butyl-4-hydroxy benzylidene)thiazol-4-one, which forms the nucleus of a number of compounds with anti-inflammatory activity, our interest has focused recently on the synthesis and chemistry of this type of compound (Song et al., 1999). In earlier studies, we synthesized new derivatives by combining condensed triazole with ibuprofen and S-naproxen, which belong to the class of 2-arylpropionic acid derivatives of non-steroidal anti-inflammatory drugs, to improve its effectiveness, and these were evaluated for their anti-inflammatory activity. In a continuation of our research programme on the synthesis of novel heterocyclic systems which have analgesic or anti-inflammatory activity, we have prepared some new 6-benzylidenethiazolo[3,2-b]-1,2,4-triazole-5(6H)-ones starting from Flurbiprofen and have determined their anti-inflammatory activity. In order to clarify the structure of this type of compounds, an X-ray structure determination of the title compound, (I), which gave a single-crystal of suitable quality, has been carried out and the results are presented here. \sch
In compound (I), the fused thiazolo[3,2-b]-1,2,4-triazole system is essentially planar. The maximum deviations from the plane of the eight-membered thiazolo-triazole system are 0.031 (6) and −0.040 (4) Å for atoms C9 and N1, respectively. The puckering parameters (Cremer & Pople, 1975) of this system are q2 0.045 (5)° and ϕ 260 (5)°. Atoms C10 and N1 are on opposite sides of the plane passing through atoms S1, C8 and C9, at distances of 0.081 (5) and 0.106 (4) Å, respectively. The thiazolo-triazole system makes dihedral angles of 34.54 (17)° with the C1—C6 ring and 86.83 (11)° with the C14—C19 ring. Rings C1—C6 and C14—C19 are almost perpendicular to each other, with a dihedral angle of 85.37 (16)°.
The C7—C8 bond is a double bond, while C1—C7 and C11—C12 are single bonds. A similar lengthening of the S1—C8 bond relative to the S1—C10 bond has been seen in the structure of a similar compound (Özbey et al., 1999).
Compound (I) is stabilized by C—H···O, C—H···N and C—H···F intermolecular contacts. The C4—H4 bond in fact forms a bifurcated contact to two acceptors, namely atoms N3 and O1 [C4—H4···O1i and C4—H4···N3i; symmetry code: (i) x − 5/4, y − 1/4, 1/4 − z] (Table 2). The bifurcated nature of the contact explains the relatively large H···A distance and relatively small D—H···A angles. Other important intermolecular contacts are C15—H15···F2ii and C23—H23···F2iii (Table 2), where atom F2 accepts hydrogen bonds from C—H donors [symmetry codes: (ii) x + 1/4, y + 1/4, 1/4 − z; (iii) x − 3/4, 3/4 − y, z − 1/4].
