Procedure

Methyl 4-azido-3-fluoro-2-((2-fluorophenyl)amino)-5-((4-methoxy benzyl)thio)benzoate can be hydrogenated catalyzed by appropriate catalyst (such as Pd/C, Pt, Ni) in the solvent (include aliphatic and aromatic hydrocarbon (such as pentane, hexane, heptane, cyclohexane, petroleum ether, petrol, gasoline, benzene, toluene, xylene), ether (such as diethyl ether, dibutyl ether, glycol dimethyl ether, 2-methoxyethyl ether, tetrahydrofuran, dioxane), ester (such as ethyl acetate, methyl acetate), amide (such as N,N-dimethylformamide, N,N-dimethylacetamide and N-methylpyrrolidin-2-one), DMSO, sulfolane, HMPA, DMPU, prefer methanol, ethanol, propan-1-ol and water) for some time (1-12 h, prefer 3-10 h). Methyl 4-amino-3-fluoro-2-((2-fluorophenyl)amino)-5-((4-methoxybenzyl)thio)benzoate is obtained after conventional workup.
