title: (2Z)-1-(5-Hy-droxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3-(4-methyl-anilino)-but-2-en-1-one.
abstract: A twist is evident in the title compound, C(21)H(21)N(3)O(2), the dihedral angle between the terminal six-membered rings being 29.46 (10)°; the linked five- and six-membered rings are coplanar [1.30 (11)°]. The carbonyl O atom accepts intra-molecular hydrogen bonds from the adjacent hy-droxy and amine groups. The three-dimensional crystal packing is achieved through C-H⋯π inter-actions.
