Procedure
2-Isopropoxy-5-nitrobenzoic acid (6.02 g, 26.75 mmol) was suspended in EtOH (100 ml) and 10% Pd on C (wet basis) (600 mg) was added. The mixture was hydrogenated at 50 psi for 2 hrs. The mixture was filtered through celite and the volatiles were removed in vacuo. The residue was triturated with IPA, and the resulting solid filtered off, washed with MTBE and dried in vacuo to give 4.15 g of 5-amino-2-isopropoxybenzoic acid (79.5%) as a pale yellow solid.
