Reaction Steps

Methyl 3-fluoro-4-nitrobenzoate (5.18 g, 26.0 mmol) in a 1:1 mixture (50 mL) of EtOH and AcOEt with 10% Pd/C (0.52 g) was hydrogenated on a Parr hydrogenation apparatus at 40 psi. Pd/C was removed by filtration through a pad of Celite® 545. The filtrate was concentrated under vacuum. The residue was diluted with AcOEt, washed with brine, and dried over anhydrous MgSO4. Evaporation of solvent under vacuum gave the title compound (4.17 g, 95% yield) as a pale solid.
