Versuchsvorschrift
To a solution of 2,2,2-trifluoro-N-[3-(4-nitrophenoxy)phenyl]acetamide (13.0 g, 39.8 mmol) in ethyl acetate (400 mL) was added 10% palladium-carbon (10 g), and the mixture was stirred at room temperature for 3 hr under a hydrogen atmosphere. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (11.7 g, 99%) as a pale-gray amorphous substance. The obtained compound was used in the next reaction without a further purification.
