Abstract: The title molecule, C₁₈H₁₁Cl₂F₃N₄O₃S, is a tricyclic amide with an overall Y shape. The dihedral angle between the pyrazole and attached benzene rings is 75.0  (1)°. In the crystal structure, an intermolecular N-HO hydrogen bond with an N_amideO_sulfonyl separation of 2.924  (5)  Å links the molecules into linear chains along the a axis.
