Comment top

Pyrazolines have been reported to exhibit a broad spectrum of biological activities including antibacterial, antifungal, anti-inflammatory, anti-depressant, antiviral agents (Nauduri & Reddy, 1998; Korgaokar et al., 1996; Udupi et al., 1998 & Bilgin et al., 1993). Some of these compounds have also shown ulcerogenic, anaesthetic and analgesic properties(Mancera et al., 1991; Kumar et al., 2003 & Nugent et al., 1993). For instance, 1-thiocarbonyl-3,5-diphenyl-2-pyrazolines exhibit antidepressant activity(Hiroshi et al., 1970), while (5-benzoyl-2,4-dihydro-3H-pyrazol-3-ylidene) bis phosphonic acid tetraethyl ester has been reported to possess novel anti-inflammatory activity. It also inhibits chronic arthritis and inflammation in animals. 3-Amino-1-[m-(trifluoromethyl)phenyl]-2-pyrazoline, besides acting as dual lipoxygenase/cycloxygenase inhibitor, attenuates postischemic brain hypoperfusion and repercussion injury(Bilgin et al., 1993). Many pyrazolines also find utility as polymer intermediates in industry(Chen et al., 1995).

In the title molecule, C₁₈H₁₇N₃O₃S, Fig.1., the dihedral angle between the two phenyl rings is 72.8 (1)°. The pyrazole ring makes a dihedral angle of 16.0 (1)° and 78.1 (1)°, with that of the methylthiophenyl and nitrophenyl rings respectively. The acetyl group is coplanar with the attached pyrazole ring, except the methyl H atoms. C—H···O, and C—H···N hydrogen bonds are found in the crystal structure; see hydrogen bond table.

Experimental top

A mixture of 1-[4-(methylthio)phenyl]-3-(4-nitrophenyl)prop-2-en-1-one (5 g, 0.016 mol) and a molar equivalent of hydrazine hydrate (80%) in glacial acetic acid (25 ml) was heated on water bath at 363–5 K for 5–6 hr. The reaction mass was then poured into ice-cold water. The solid obtained was filtered, washed with water, dried and crystallized from methanol to yield the title compound. Yield 5.2 g (88%),

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
