The crystal structure of the title compound, C 18 H 18 FN 3 O 4 , was published [Li et al. (2005). Acta Cryst. E 61 , 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—H⋯O hydrogen bond with the carbonyl O atom.
