(E)-5-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino-meth-yl]-2-meth-oxy-phenyl 4-chloro-benzene-sulfonate.
In the title compound, C(25)H(22)ClN(3)O(5)S, the two N atoms in the pyrazole ring have a pyramidal environment, with the sums of the valence angles around them being 349.3 (2) and 357.5 (2)°. The phenyl ring is twisted by 50.97 (12)° from the pyrazole mean plane. In the crystal, pairs of weak C-H⋯O hydrogen bonds link the mol-ecules into inversion dimers.
