Versuchsvorschrift
A mixture of 3-nitro-4-fluorobenzoic acid (1.85 g, 10.0 mmol) in MeOH (10 mL) and 5% Pd/C (100 mg) was stirred under an atmosphere of hydrogen and for 6 h. The catalyst was removed by filtration, washed with methanol and the volatiles were removed in vacuo to give compound 8A, 3-amino-4-fluorobenzoic acid, as a light yellow solid (1.50 g, 9.67 mmol, 97%).
