In the title Schiff-base type compound, C18H13N3O5, the central furan ring makes dihedral angles of 12.80 (7) and 51.43 (4)° with the terminal benzene rings. The dihedral angle between the benzene rings is 45.43 (3)°. In the crystal, C—H
O hydrogen bonds link the molecules into layers parallel to (010). In addition, there are π–π stacking interactions within the layer [centroid–centroid distance = 3.584 (1) Å] and between the layers [centroid–centroid distance 3.751 (1) Å].

The title compound, C19H26N2O3, crystallizes with two independent molecules in the asymmetric unit which differ in the twist of the phenyl rings with respect to the plane of the amide group [the C—C—C—O torsion angles are 121.5 (3) and −119.6 (3)° in the two molecules. Both cyclohexane rings adopt chair conformations. In the crystal, weak C—HO interactions occur. The crystal studied was a non-merohedral twin with a minor component of 4.8 (1)%.
O interactions occur. The crystal studied was a non-merohedral twin with a minor component of 4.8 (1)%.
