چکیده

There are two unique mol-ecules in the asymmetric unit of the title compound, C(17)H(15)NO(4), which are linked into chains via inter-molecular N-H⋯O and C-H⋯O inter-actions; the chains are linked via weak C-H⋯O inter-actions, forming a parallel sheet structure. The molecule is approximately planar, with dihedral angles of 19.91 (4) and 11.06 (4)° between the naphthyl ring and the amino-methyl-ene group, and between the amino-methyl-ene unit and the planar part of the dioxane ring, respectively. The dioxane ring adopts a half-boat conformation, with the C atom between the dioxane O atoms 0.595 (8) Å out of the plane through the remaining atoms. The mol-ecule has an intra-molecular N-H⋯O hydrogen bond which stabilizes the planar conformation.
