Procedure

1,1-Dimethylethyl N-((5-fluoro-4-hydroxy-1,1-dimethyl-2-oxo-naphthalen-3-yl)carbonyl)glycinate (116 mg, 319 μmol) was stirred in TFA (5 mL) for 15 minutes. The solvent was then removed in vacuo, and the residue was partitioned between DCM and water. The DCM layer was removed, and the solvent was removed in vacuo to give the product as a light yellow solid. MS m/e=308 (M+H)+. Calculated for C15H14FNO5 307.09.
