In the title compound, C19H17Cl2N3O2, there are three molecules (A, B and C) in the asymmetric unit and each differs in the conformation adopted. 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 44.5 (2) and 56.2 (2), respectively in A, 51.1 (2) and 54.1 (2) in B, and 53.8 (2) and 54.6 (2) in C. The dihedral angles between the dichlorophenyl and 2,3-dihydro1H-pyrazol-4-yl rings are 54.8 (2), 76.2 (2) and 77.5 (2) in molecules A, B and C, respectively, while the 2,3-dihydro-1Hpyrazol-4-yl and phenyl rings make dihedral angles of 45.3 (2), 51.2 (2) and 42.8 (2), respectively. In the crystal, two of the molecules are linked through N—HO hydrogen bonding to an adjoining molecule, forming dimers of the R2 2 (10) type, while the third molecule forms such dimers with itself. C— HO interactions link the dimers.
