The asymmetric unit of the title compound, C 19 H 16 FN 5 O 4 , contains two independent molecules. The dihedral angles between the main planes and the fluorophenyl rings in the two molecules are 83.24 (5) and 71.76 (4) . Weakstacking interactions may be effective in the stabilization of the crystal
