title: 1-[5-Acetyl-2,6-dimethyl-4-(5-phenyl-1H-pyrazol-3-yl)-1,4-dihydro-pyridin-3-yl]ethanone monohydrate.
abstract: In the title compound, C(20)H(21)N(3)O(2)·H(2)O, the aza-substitued six-membered ring adopts a (L4)B conformation. In the crystal, classical N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds connect the entities into a three-dimensional network. Intra-molecular C-H⋯O contacts are also observed.
