چکیده
In the title compound, C(19)H(19)NO(5), the furan-one unit makes a dihedral angle of 30.93 (6)° with the benzene ring and a dihedral angle of 9.51 (6)° with the aniline ring. In the crystal, inter-molecular C-H⋯O hydrogen bonds and C-H⋯π contacts link the mol-ecules into sheets. A weak intramolecular hydrogen bond is also observed.
