Abstract: In the title compound, C₁₉H₁₇Cl₂N₃O₂, the amide group is planar and, through N-HO hydrogen bonding to an adjoining molecule, forms dimers of the R₂²(10) type. As a result of steric repulsion, the amide group is rotated with respect to both the dichlorophenyl and 2,3-dihydro-1H-pyrazol-4-yl rings, making dihedral angles of 71.63 (11) and 57.93 (10)°, respectively. The dihedral angle between the dichlorophenyl and 2,3-dihydro-1H-pyrazol-4-yl rings is 76.60 (10)° while that between the 2,3-dihydro-1H-pyrazol-4-yl and phenyl rings is 49.29 (7)°. The crystal structure also features weak C-HO interactions.
