(E)-2-Bromo-4-[(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino­meth­yl]-6-meth­oxy­phenyl 4-methyl­benzene­sulfonate

In the title compound, C26H24BrN3O5S, the central benzene ring makes dihedral angles of 6.27 (6), 33.63 (6) and 69.31 (5)°, respectively, with the pyrazolone ring, the bromo­benzene ring and the terminal phenyl ring. An intra­molecular C—H⋯O hydrogen bond occurs. The crystal packing features weak non-classical C—Br⋯O inter­actions [Br⋯O = 3.222 (2) Å] that form inversion-related dimers
