The asymmetric unit of the title compound, C22H21N3O2, consists of two independent mol­ecules (A and B) having differing conformations. The differences mainly concern the dihedral angles which the hy­droxy­phenyl and di­methyl­phenyl rings subtend to the central phenyl­ene ring, these being 30.16 (6) and 58.60 (6)° in mol­ecule A and 13.42 (7) and 60.31 (7)° in B. With the exception of the dimethyphenyl substituent, the conformations of the rest of each mol­ecule are largely determined by intra­molecular O—H⋯N and N—H⋯O hydrogen bonds. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into chains extending parallel to the a axis in which the types of mol­ecules alternate in an …ABAB… fashion.

The antiphlogistic non-steroidal anti-inflammatory drugs (NSAIDs) mefenamic acid [2-(2,3-dimethylphenylamino)-benzoic acid], is a potent cyclo-oxygenase inhibitor (Nawaz et al., 2007). Mefenamic (MA) acid also has therapeutic potential in Alzheimer's disease (Joo et al., 2006). Masking the free carboxylic group in MA like other NSAIDs could suppress the side effect such as gastrointestinal toxicity (Arun & Ashok, 2009; Tammara et al., 1994). On other hand, hydrazide-hydrazone compounds are found to be associated with various biological activities such as antimicrobial, anti-convulsant, analgesic, anti-inflammatory, anti-platelet, anti-tubercular and anti-tumor properties (Bedia et al., 2006; Rollas et al., 2002; Palaska et al., 2002; Rollas & Küçükgüzel, 2007). Based on such facts, and as part of our ongoing study on the functionalization of (NSAIDs), we report herein the synthesis and the crystal structure of the title compound.

The asymmetric unit of the title compound consists of two independent molecules (A and B) having differing conformations. Differences reside mainly in the dihedral angles which the hydroxyphenyl and dimethylphenyl rings make with the central phenylene ring, being 30.16 (6) and 58.60 (6)° in one of the molecules (A) and 13.42 (7) and 60.31 (7)° in the remaining one (B). With the exception of the dimethyphenyl substituent, the conformations of the rest of each molecule are largely determined by intramolecular O—H···N and N—H···O hydrogen bonds (Fig. 1 and Table 1). Intermolecular N—H···O hydrogen bonds form chains extending parallel to the a axis (Fig. 2 and Table 1) where molecules on both types alternate in a.. A···B···A···B.. fashion.

Experimental top

A mixture of equimolar ratio of Mefenamic acid hydrazide (1 mmol, 255 mg) and salicaldehyde (1 mmol, 122 mg) with catalytic amount of glacial acetic acid was refluxed for 5 h. On cooling, the precipitate was separated then collected and recrystallized from ethanol to furnish the title compound as brown crystals with m.p= 457–459 K.

Refinement top

H-atoms attached to carbon were placed in calculated positions (C—H = 0.95 - 0.98 Å) and included as riding contributions with isotropic displacement parameters 1.2 - 1.5 times those of the attached atoms. H-atoms attached to nitrogen and to oxygen were placed in locations derived from a difference map and refined freely. In order to adjust distances of hydrogen atoms of the NH and OH groups DFIX instruction was used with the target value of 0.85 (2) Å (O1—H1O, N2—H2N, N3—H3N, O3—H3O, N5—H5N and N6—H6N).

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 on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
