چکیده
In the title compound, C(17)H(19)NO(3), the mol-ecule has an E configuration with respect to the C=N bond and the dihedral angle between the aromatic rings is 56.07 (5)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds occur. The dimers are linked by weak C-H⋯π inter-actions, forming a three-dimensional network.
