Procedure
Benzyl 4-azido-5-(benzyloxy)-3-fluoro-2-((2-fluorophenyl)amino)benzoate can be hydrogenated in the presence of appropriate catalyst (such as Pd/C, Pt, Ni). The reaction normally completes within several hours (1-12 h, prefer 3-10 h). 4-Amino-3-fluoro-2-((2-fluorophenyl)amino)-5-hydroxybenzoic acid is obtained after conventional workup.
