Abstract: The crystal structure of the title compound, C₁₈H₁₈FN₃O₄, was published [Li et al. (2005). Acta Cryst. E61, o2235-o2236] with an error in the chemical formula and without location of the carboxyl H atom. This has now been corrected. The missing H atom was located and refined. This H atom is involved in an intramolecular O-HO hydrogen bond with the carbonyl O atom.
