The title compound, C29H25N3O3S, crystallizes in the monoclinic P21/n. The molecule contains a central four-ring system in which all of the rings are almost coplanar. Both the 4-methoxyphenyl ring and the prop-2-ynyloxy substituent are disordered over two equivalent conformations with occupancy ratios of 0.903 (2):0.097 (2) and 0.776 (5):0.224 (5), respectively. In the crystal, π–π interactions [centroid–centroid distance = 3.7327 (11) Å] between the dihydropyrazole ring and the 4-methoxyphenyl ring link the molecules into centrosymmetric dimers. In addition, there are weak C—H⋯S, C—H⋯N and C—H⋯O interactions, which link the molecules into a complex three-dimensional array.

Structure description
Pyrazoles and thiazoles are important scaffolds for developing target drug molecules and exhibit a variety of pharmacological activities including antibacterial (Tanitame et al., 2004), antifungal (Hassan, 2013), anti-inflammatory (Farghaly et al., 2000), antidepressant (Secci et al., 2011), antianalgesic (Jamwal et al., 2013), anticancer (Keter & Darkwa, 2012), anitubercular (Kumar et al., 2020), antiviral (Rashad et al., 2008) and antidiabetic activity (Datar & Jadhav, 2013). The design, efficient synthesis and molecular docking of some thiazolyl-pyrazole derivatives as anticancer reagents have been reported (Sayed et al., 2019). We have recently reported the formation of 1-(thiazol-2-yl)-4,5-dihydropyrazoles from simple precursors: synthesis, spectroscopic characterization and the structures of an intermediate and two products (Mahesha et al., 2021). A series of 1,3-thiazole integrated pyrazoline scaffolds have been synthesized and characterized (CSD refcodes DADQIL, DADQEH; Salian et al., 2017). The synthesis, fluorescence, TGA and of a thiazolyl-pyrazoline derived from has been described (JUNRAN; Suwunwong et al., 2015). In addition, the following crystal structures of related compounds have been reported: 2-[3-(4-bromophenyl)-5-(4-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl]-4-phenyl-1,3-thiazole (IDOMOF; Abdel-Wahab et al., 2013c), 2-[5-(4-fluorophenyl)-3-(4-methylphenyl)-4,5-dihydro-1H-pyrazol-1-yl]-4-phenyl-1,3-thiazol (MEWQUC; Abdel-Wahab et al., 2013a), 2-[3-(4-chlorophenyl)-5-(4-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl]-4-phenyl-1,3-thiazole (WIGQIO; Abdel-Wahab et al., 2013b), 2-[3-(4-chlorophenyl)-5-(4-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl]-8H-indeno[1,2-d]thiazole (WOCFEC; El-Hiti et al., 2019) and 2-[3-(4-bromophenyl)-5-(4-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl]-8H-indeno[1,2-d]thiazole (PUVVAG; Alotaibi et al., 2020).
With this in mind, the present study was planned to synthesize a ring system that contains both pyrazole and thiazole in a single molecule with an acetylene substituent, which can further be modified into highly functionalized heterocycles (Larock & Yum, 1991; Sonogashira, 2002). A related molecule, 4, [5-(4-fluorophenyl)-1-[4-(4-methylphenyl)thiazol-2-yl]-3-[4-(prop-2-ynyloxy)phenyl]-4,5-dihydro-1H-pyrazole] has been published recently (Archana et al., 2022). This paper reports the synthesis and of the title compound, C29H25N3O3S, (3), which crystallizes in the monoclinic P21/n, with four molecules in the In order to assist the discussion, the rings are labeled as C7–C12 (A), C4–C6/N3/S1 (B), C1–C3/N1/N2 (C), C21–C26 (D), and the major component of the disordered 4-methoxyphenyl ring, C14–C19 (E). Ring E is disordered over two equivalent conformations with occupancies of 0.903 (2):0.097 (2) and the two components are slightly twisted with respect to each other [dihedral angle of 2.3 (9)°]. The prop-2-ynyloxy substituent on ring D is also disordered over two equivalent conformations with occupancies of 0.776 (5) and 0.224 (5) (see Fig. 1). The central four-ring system (rings A–D) is almost planar [dihedral angles between A and B, B and C and C and D of 13.1 (1), 10.9 (1) and 4.6 (1)°, respectively]. These dihedral angles are not cumulative as the dihedral angle between the two terminal rings, A and D, is 3.1 (1)°. Interestingly and similar to the structure of 4, ring C, which contains two sp3 carbon atoms, C1 and C2, is close to planar with an r.m.s. deviation from planarity of only 0.044 (1) Å. One reason (or consequence) of this planarity is that it minimizes steric repulsion between the H atoms attached to C2 and H22A attached to C22 of the adjacent ring D. As would be expected, the dihedral angle between rings C and E is close to 90 [88.44 (6)°]. As in structure 4, there are π–π interactions between rings A and C, which link the molecules into centrosymmetric dimers [centroid–centroid distance = 3.7327 (11) Å, with a slippage of 1.275 Å]. In addition, there are weak C—H⋯S and C—H⋯N interactions, which link the molecules into a complex three-dimensional array (see Table 1, Fig. 2).
Synthesis and crystallization
1-(p-Propyloxyphenyl)-3-(p-fluorophenyl)prop-2-ene-1-one (1) was obtained by the base-catalyzed condensation of p-propylyoxyacetophenone with p-fluorobenazaldehyde in an ethanol medium employing sodium hydroxide as catalyst. This propenone (1) upon treatment with thiosemicarbazide in alcoholic potassium hydroxide gave compound (2).
4,5-Dihydro-3-(4-methoxyphenyl)-5-[4-(prop-2-ynyloxy)phenyl]pyrazole-1-carbothioamide (2) (1 g, 0.002 mol) in ethanol (20 ml), 4-methoxyphenacyl bromide (0.5 g, 0.002 mol) and sodium acetate (0.162 g, 0.002 mol) were heated at reflux for 1 h. After cooling, the obtained product was collected by filtration and crystallized from the mixed solvents of ethanol and DMF (3:2). The reaction scheme shown in Fig. 3. Yield: 84%, m.p.: 486–488 K.

Refinement
Crystal data, data collection and structure 3 are summarized in Table 2. Both the 4-methoxyphenyl and the 4-prop-2-ynyloxy groups were found to be disordered over two conformations with occupancies of 0.903 (2)/0.097 (2) and 0.776 (5)/0.224 (5), respectively.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. All hydrogen atoms were placed geometrically and refined as riding atoms with their Uiso values 1.2 times that of their attached atoms (1.5 times for CH3 groups). |
