(Received 14 February 2011; accepted 16 February 2011; online 23 February 2011)

In the title compound, C27H21N3O2, the non-H atoms of the meth­oxy­phenyl­acryloyl substitutent of the pyrazolyl ring are almost co-planar (r.m.s. deviation = 0.070 Å), and the mean plane is twisted by 18.7 (1)° with respect to the pyrazolyl ring. The phenyl and tolyl substituents are aligned at 48.9 (1) and 44.5 (1)° with respect to the pyrazolyl ring. Weak inter­molecular C—H⋯O and C—H⋯N hydrogen bonding is present in the crystal structure.

Supporting information


Comment top

We have reported the antitumor activity of aryl-pyrazoles against CaCo-2 and HEP-2 cell lines (Abdel-Aziz et al., 2010). Among these is the title compound (Scheme I), whose biological properties will be reported elsewhere (Abdel-Aziz et al., 2011). The compound has methoxyphenylacryloyl, phenyl and tolyl substituents in the pyrazolyl ring. The methoxyphenylacryloyl substituent is twisted by 18.7 (1)° with respect to the pyrazolyl ring; the phenyl and tolyl substituents are aligned at 48.9 (1)° and 44.5 (1)° with respect to the five-membered ring (Fig. 1).

Experimental top

The synthesis will be reported elsewhere (Abdel-Aziz et al., 2011). 3-Acetyl-5-phenyl-1-p-tolyl-1H-pyrazole-4-carbonitrile (10 mmol) was reacted with 4-methoxybenzaldehyde (10 mmol) in presence of sodium ethoxide solution (prepared by dissolving 0.23 g sodium metal in 50 ml absolute ethanol). The compound was recrystallized from an ethanol-DMF (3:1) mixture.

Refinement top

Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 to 0.98 Å, Uiso(H) 1.2 to 1.5Ueq(C)] and were included in the refinement in the riding model approximation.
