title: (E)-4-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino-meth-yl]-2-meth-oxy-phenyl 4-bromo-benzene-sulfonate.
abstract: In the title compound, C(25)H(22)BrN(3)O(5)S, the central benzene ring makes dihedral angles of 4.41 (10), 67.09 (9) and 62.05 (10)°, respectively, with the pyrazolone, bromo-benzene and terminal phenyl rings. The dihedral angle between the pyrazolone and phenyl rings is 57.75 (11)°. In the crystal, two pairs of C-H⋯O hydrogen bonds link the mol-ecules into inversion dimers. A weak intra-molecular C-H⋯O hydrogen bonds is also observed.
