【 摘 要 】

The asymmetric unit of the title compound, C20H20N2O3·H2O, contains two independent mol­ecules (A and B), with similar conformations and two independent water mol­ecules. In the crystal, N—H⋯O and Owater—H⋯O hydrogen bonds link all moieties into two crystallographically independent kinds of sheets parallel to the ac plane. These independent sheets, each containing either A or B mol­ecules, are further alternately stacked along the b axis and inter­connected via C—H⋯πar­yl inter­actions.
