Reaction Steps
A mixture of 4-fluoro-2-methyl-5-nitro-phenol (1.4 g, 8.2 mmol) and 10% Pd/C (0.3 g, 20%/w) in MeOH (80 mL) was stirred under H2 (30 psi) for 2 h. The Pd/C was removed by filtration and the filtrate was concentrated to give 5-amino-4-fluoro-2-methyl-phenol (0.68 g, 62% yield). 1H NMR (300 MHz, DMSO-d6) δ 8.75 (s, 1H), 6.62 (d, J=12.0 Hz, 1H), 6.21 (d, J=8.1 Hz, 1H), 4.69 (s, 2H), 1.93 (s, 3H).
