A mixture of 3-dimethylamino-1-[4-methyl-2-(methyl-o-tolyl-amino)-thiazol-5-yl]-propenone (1.575 g, 5 mmol) and NaOH (0.2 g, 5 mmol) in 2-methoxylethanol (20 ml) was treated with N-m-tolyl-guanidine carbonate (1.58 g, 7.5 mmol). The reaction mixture was heated at 383 K under N2 for 11 h. After concentration, the residue was filtered and washed liberally with ethanol and water. Recrystallization from acetone affored the title compound as dark yellow crystals, 1.17 g, m.p.455–458 K, yield 58.5%. Since the crystal product was not found to be suitable for X-ray diffraction studies,a few crystals were dissolved in 2-butanone, which was allowed to evaporate slowly to give yellow crystals of (I) suitable for X-ray diffraction studies. 1H NMR(CDCl3, TMS, 400 MHz, δp.p.m.): 8.24 (d, 1H, J = 5.2 Hz, py—H), 7.65 (s, 1H, Ar—H), 7.36–7.27 (m, 4H, Ar—H), 7.13–7.09 (m, 2H, Ar—H), 6.92 (s, 1H, Ar—H), 6.79 (d, 1H, J = 5.6 Hz, py—H), 3.49 (s, 3H, CH3), 2.61 (s, 3H, CH3), 2.29 (s, 3H, CH3), 2.15 (s, 3H, CH3).

All H atoms were placed in calculated positions (C—H 0.95–0.98 Å and N—H 0.87–0.89 Å) and refined as riding with Uiso(H) = 1.2–1.22Ueq of the parent atom.

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. |

Thiazole derivatives are found to be associated with various biological activities (Narayana et al., 2004). In order to further study the structure-activity relationship (SAR) of the thiazolyl-pyrimidine derivatives, we introduced arylamino group into 2-position of thiazole ring of thiazolyl-pyrimidine according to the general pyrimidine condensation method of Bredereck (Bredereck et al., 1964). But, it was found that the obtained compound was not desired compound that confirmed by 1H NMR, MS. So, the structure of (I) was further determined using single-crystal X-ray diffraction.
The molecular structure of (I) is illustrated in Fig. 1. The thiazole ring (S1/C7/N2/C8/C9) and the pyrimidine ring (C10/C11/C12/N3/C13/N4) are almost planar, with a dihedral angle of 4.02 (9)°. The aniline rings (C1/C2/C3/C4/C5/C6/N1) and (C14/C15/C16/C17/C18/C19/N5) make dihedral angles of 80.96 (11) Å and 14.15 (9) Å with the thiazole ring, respectively. In the thiazole ring, the bond lengths S1—C7 [1.739 (2) Å], S1—C9 [1.748 (18) Å] and N2—C8 [1.372 (2) Å] correspond to typical single bond, and the C7—N2 [1.312 (2) Å], C8—C9 [1.373 (3) Å] belong to typical for double bonds. The crystal structure is stabilized by intermolecular weak N—H···N interactions (Fig. 2). Furthermore, every two molecules containing two N—H···N hydrogen bondings consists a dimer as octagon.
