Reaction Steps

To a solution of benzyl 4-azido-5-benzyloxy-3-fluoro-2-((2-fluorophenyl)amino)benzoate (14.63 g, 30.07 mmol) in MeOH (200 mL) was added and 10% palladium on carbon (2.55 g) under nitrogen atmosphere. Then the nitrogen atmosphere was completely changed to hydrogen atmosphere. The mixture was stirred for 6 h at ambient temperature. After the insoluble matter was filtered off, the solvent was concentrated in vacuo to give the crude product (7.58 g, 90% yield), which was used directly in next step without further purification.
