Both the acetyl and phenyl substituents of the central pyrazole ring in the title compound, C24H20N2O3S, are twisted with respect to the pyrazole ring, with the twist involving the phenyl ring being greater [67.4 (1) and 29.6 (2)°]. The tolyl substituent is disordered over two positions in a 1:1 ratio; the mean planes of the aromatic ring are aligned at 67.7 (3) and 69.4 (3)° with respect to the pyrazole ring.

We have recently reported the synthesis of the compound (Nasser et al., 2011). Crystals were obtained upon recrystallization from ethanol suitable for X-ray structural analysis was obtained by slow evaporation from ethanolic solution at room temperature.
Carbon-bound H-atoms were placed in calculated positions (C–H 0.93–0.96 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2–1.5U(C).The tolyl group is disordered over two positions; the occupancy could not be refined, and was assumed to be a 1:1 type of disorder. The benzene rings were refined as rigid hexagons of 1.39 Å sides. The temperature factors of the primed atoms were set to those of the unprimed ones, and all anisotropic temperature factors were restrained to be nearly isotropic. The pair of N–Ctolyl distances were restrained to within 0.01 Å of each other as were the pair of Cmethyl–Cphenylene bonds.
Omitted because of bad agreement were (0 8 0), (-2 18 8) and (-8 10 13).

1-[1-(3-Methylphenyl)-5-phenyl-4-(phenylsulfanyl)-1H-pyrazol-3-yl]ethanone (Scheme I) exhibited excellent activity compared with a standard drug, indomethacin, when tested as an anti-inflammatory chemical. The high activity has been rationalized by using molecular docking (Nasser et al., 2011). Both the acetyl and phenyl substituents of the central pyrazole ring are twisted with respect to the pyrazole ring, with the twist involving the phenyl ring being greater (67.4 (1) ° and 29.6 (2) °). The tolyl substituent is disordered over two positions in a 1:1 ratio; the mean planes of the aromatic ring are aligned at 67.7 (3) ° and 69.4 (3) ° (Fig. 1).
