چکیده

The title compound, C(25)H(22)N(2)O(4)S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007 Å) and the N- and C-bound phenyl rings are 48.10 (7) and 72.01 (7) °, respectively, indicating that the planes through the residues are significantly twisted from the plane through the heterocycle. The ester-CO(2) group is also twisted out of this plane, with an O-C-C-N torsion angle of -29.04 (11)°. The sulfonyl-O atoms lie to one side of the pyrazole plane and the sulfonyl-phenyl ring to the other. The dihedral angle between the two ring planes is 70.63 (7) °. Supra-molecular arrays are formed in the crystal structure sustained by C-H⋯O and C-H⋯π(pyrazole) inter-actions and methyl-C-H⋯π(N-bound benzene) contacts.
