実験手順
To a stirred solution of 2-fluoro-1-(2-methoxyethoxy)-4-nitrobenzene (2.5 g, 11.62 mmol, 1.0 eq.) in ethanol (20 mL) was added 10% Pd/C (500 mg) and stirred in hydrogen gas atmosphere for 16 h at RT. The catalyst was filtered over a celite pad and the filtrate was concentrated to get 3-fluoro-4-(2-methoxyethoxy)aniline (2.0 g, 93.9%; TLC system: EtOAc/PE (3:7), Rf: 0.3).
