To a solution of compound benzyl 4-azido-5-(benzyloxy)-2-((2-chlorophenyl)amino)-3-fluorobenzoate (22.97 g, 45.67 mmol) in MeOH (500 mL) was added and 10% palladium on carbon (3.80 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 under reduced pressure to give the desired product, which was used directly in the next step without further purification.
