Ethyl 1-(4-methylphenyl)-5-phenyl-4-phenylsulfonyl-1H-pyrazole-3-carboxylate

The title compound, C25H22N2O4S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007 angstrom) and the N- and C-bound phenyl rings are 48.10 (7) and 72.01 (7) degrees, respectively, indicating that the planes through the residues are significantly twisted from the plane through the heterocycle. The ester-CO2 group is also twisted out of this plane, with an O-C-C-N torsion angle of -29.04 (11)degrees. The sulfonyl-O atoms lie to one side of the pyrazole plane and the sulfonylphenyl ring to the other. The dihedral angle between the two ring planes is 70.63 (7)degrees. Supramolecular arrays are formed in the crystal structure sustained by C-H center dot center dot center dot O and C-H center dot center dot center dot pi(pyrazole) interactions and methyl-C-H center dot center dot center dot pi (N-bound benzene) contacts.
