Abstract: In the molecule of the title compound, C₂₇H₂₁ClN₂O₄, the dihedral angle between the furan rings is 67.00 (3)°. The chlorophenyl ring is oriented at dihedral angles of 76.61 (3) and 69.36 (3)° with respect to the furan rings. An intramolecular N-HO interaction results in the formation of an eight-membered ring with a twisted conformation. In the crystal structure, intermolecular N-HO and C-HO interactions link the molecules into a three-dimensional network, forming R₂²(16) ring motifs. Three weak C-H interactions are also found.
