In the title molecule, C24H20N2O2S, the thiazole and amide groups are essentially coplanar. The thiazole ring forms dihedral angles of 61.62 (4) and 26.75 (5)° with the benzene rings of the methoxyphenyl and methylphenyl groups, respectively, and 33.69 (6)° with the phenyl ring. The crystal packing is stabilized by intermolecular C—H⋯O hydrogen bonds, forming a three-dimensional network.

The title compound was prepared according to the method reported earlier (Saeed & Parvez 2006). Single crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethanol solution. Full spectroscopic and physical characterization will be reported elsewhere.
Hydrogen atoms were located in difference syntheses, refined at idealized positions riding on the C (C–H = 0.95–0.98 Å) atoms with isotropic displacement parameters Uiso(H) = 1.2U(Ceq) and 1.5(methyl-C). Methyl H atoms were refined on the basis of rigid groups allowed to rotate but not tip.
2-Imino derivatives of 1,3-thiazolines posses a wide range of pharmacological and synthetic applications. Thus, these show potent bioactivities ranging from antitubercular (Shehata et al., 1996) to anti-HIV (Venkatachalan et al., 2001) activities. Iminothiazolines containing a pyrazine ring show significant antibacterial and antimicrobial activity (Bonde & Gaikwad 2004), derivatives of rhodanine show antibacterial, anti-inflammatory and antiviral activities (Lee & Sim et al., 2000) and bis-thiazoline derivatives show marked anti-cancer activity against human cell lines (Arcadi et al., 2003). A 2-imino-1,3-thiazoline derivative KHG22394 acts as a skin whitening agent (Kim et al., 2007).

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. |

2-Imino derivatives of 1,3-thiazolines posses a wide range of pharmacological and synthetic applications. Thus, these show potent bioactivities ranging from antitubercular (Shehata et al., 1996) to anti-HIV (Venkatachalan et al., 2001) activities. Iminothiazolines containing a pyrazine ring show significant antibacterial and antimicrobial activity (Bonde & Gaikwad 2004), derivatives of rhodanine show antibacterial, anti-inflammatory and antiviral activities (Lee & Sim et al., 2000) and bis-thiazoline derivatives show marked anti-cancer activity against human cell lines (Arcadi et al., 2003). A 2-imino-1,3-thiazoline derivative KHG22394 acts as a skin whitening agent (Kim et al., 2007).
