Procedure
To a solution of methyl 2-[4-fluoro-3-({[3-(trifluoromethyl)phenyl]acetyl}amino)phenoxy]-5-nitrobenzoate (3.75 g, 7.62 mmol) in methanol (40 mL)/tetrahydrofuran (8 mL) solution was added 10% palladium-carbon (400 mg), and the mixture was stirred at room temperature for 6 hr under a hydrogen atmosphere (1 atm). Insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (ethyl acetate/n-hexane=30/70→80/20), and the fraction containing the object product was concentrated under reduced pressure to give the title compound (3.09 g, 87%) as a yellow oil.
