Versuchsvorschrift
Ethyl 2-fluoro-5-nitrobenzoate (0.63 g) was dissolved in ethanol (10 ml), and 10% Pd—C (0.064 g) was added to the solution. The mixture was subjected to catalytic reduction at room temperature for 7 hr. The reaction solution was filtered through Celite, and was washed with ethanol. The solvent was then removed by distillation under the reduced pressure to give 0.55 g (100%) of ethyl 5-amino-2-fluorobenzoate.
