A mixture of 1-fluoro-4-(4-nitrophenoxy)benzene (6.4 g, 27.44 mmol, 1.00 equiv) and 10% palladium on carbon (1 g) catalyst in methanol (200 mL) was stirred under 1 atmosphere of hydrogen at room temperature for 4 h. The catalyst was removed by filtration and the filtrate was concentrated under vacuum to give 5.4 g (97%) of 4-(4-fluorophenoxy)benzenamine as an off-white solid. 1H-NMR (300 MHz, CDCl3): δ 6.99-6.82 (m, 6H), 6.68 (d, J=8.7 Hz, 2H), 3.63 (br, 2H) ppm.
