Procedure

4-Cyclohexylamino-2-methyl-3-nitrobenzoic acid methyl ester (150 mg) was dissolved in THF/MeOH (30 mL, 1:2 ratio) and stirred in the presence of H2 (1 atm) and a catalytic amount of Pd(OH)2 (20 mg) at room temperature for 14 h. The reaction mixture was then filtered, evaporated to dryness and purified by flash column chromatography, using 25% EtOAc in hexane with 0.2% NH4OH as the eluent, to give the pure aniline (106 mg).
