Methanol → Methyl 3-amino-5-fluorobenzoate

Participants

Reaction Steps

To a solution of 3-amino-2-bromo-5-fluorobenzoate (2.48 g, 10 mmol) in MeOH (80 mL) was added Pd/C (0.5 g, 5%, 50% water), the mixture was stirred at atmosphere of hydrogen for about 6.0 h. Then the mixture was filtered, washed with MeOH (10 mL). The filtrate was concentrated and recrystallized with MeOH (2.5 mL) to afford methyl 3-amino-5-fluorobenzoate (1.48 g, 88%) as a brown solid. 1H NMR (DMSO-d6) δ 7.04 (t, 1H, J=1.8 Hz), 6.74-6.76 (m, 1H), 6.55-6.80 (m, 1H), 6.58 (m, 1H), 3.82 (s, 3H).
