Procedure

To a solution of N-[5-(2-cyano-4-nitrophenoxy)-2-fluorophenyl]-2-[3-(trifluoromethyl)phenyl]acetamide (1.36 g, 2.96 mmol) in ethanol (25 mL)/tetrahydrofuran (10 mL) was added 10% palladium-carbon (160 mg), and the mixture was stirred at room temperature for 5 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→100/0), and the fraction containing the object product was concentrated under reduced pressure to give the title compound (1.17 g, 92%) as a beige amorphous form.
