In the title compound, C(25)H(22)BrN(3)O(5)S, the central benzene ring makes dihedral angles of 32.02 (14), 37.49 (18) and 80.52 (13)°, respectively, with the pyrazolone ring, the bromo-benzene ring and the terminal phenyl ring. This conformation features a short intramolecular C-H⋯O contact that generates an S(6) ring. In the crystal, inversion dimers linked by pairs of C-H⋯O=C hydrogen bonds occur. ...[more]
