Yield:399-95-1 100%
Reaction Conditions:
with hydrogen;palladium 10% on activated carbon in tetrahydrofuran;ethanol at 20; for 4.5 h;
Steps:
107
To a solution of 3-fluoro-4-nitrophenol (20 g) in ethanol (200 ml)-tetrahydrofuran (125 ml) was added 10% palladium carbon (6.0 g), followed by stirring under a hydrogen atmosphere at room temperature for 4.5 hrs. The mixture was filtered to remove the catalyst, which was washed with ethanol. The filtrate was concentrated under a reduced pressure to provide the titled compound (16.1 g, 100%) as a pale yellow solid. 1H-NMR Spectrum (DMSO-d6) δ (ppm): 4.38 (2H, m), 6.34 (1H, m), 6.43 (1H, m), 6.59 (1H, dd, J=8.4, 10.4 Hz), 8.78 (1H, s).
