The crystal structure is shown in the figure. Tables 1 and 2 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters.

Data collection and handling.

Table 2:

Fractional atomic coordinates and isotropic or equivalent isotropic displacement parameters (Å2).

Source of material

Reaction of 3-(benzofuran-2-yl)-5-(4-fluorophenyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide and 2-bromo-1-(4-chlorophenyl)ethanone in ethanol under reflux for 3 h provided the crude product. Crystallization from dimethylformamide gave colorless crystals of the title compound (Mp 176–178 °C) [1].

Experimental details

Cell refinement and data reduction were carried out by Bruker SAINT [6].

Discussion

Pyrazolylthiazole derivatives exhibit anti-inflammatory [2], antimicrobial activities [2] and cause antinociception in mice [3]. Also, some derivatives are useful as DF508-cystic fibrosis transmembrane conductance regulators that have improved hydrophilicity compared to bithiazoles [4].

The asymmetric unit of the title structure contains only one independent molecule with a central pyrazol ring (N1/N2/C9—C11) which makes dihedral angles of 1.05 (2)°, 2.85 (2)° and 77.25 (3)° with benzofuran ring (O1/C1—C8), thiazol ring (S1/C18/N3/C19/C20) and fluorophenyl ring (C12—C17), respectively. There is one hydrogen bond: C23—H23A⋯F1i with symmetry code: i = −x+1, y+1/2, −z+1/2.
