Procedure

To a solution of methyl 4-azido-5-(benzylthio)-3-fluoro-2-((2-fluoro phenyl)amino)benzoate (19.43 g, 45.56 mmol) in MeOH (500 mL) was added and 10% palladium on carbon (3.40 g) under nitrogen atmosphere. Then the nitrogen atmosphere was completely changed to hydrogen atmosphere. The mixture was stirred for 3 h at ambient temperature. After the insoluble matter was filtered off, the solvent was evaporated in vacuo to give the desired product (18.06 g, 99.0%). 1H NMR (400 MHz, CDCl3): δ 9.08 (s, 1H), 7.78 (s, 1H), 7.11 (m, 9H), 4.65 (s, 2H), 3.88 (s, 2H), 3.84 (s, 3H).
