A solution of 2-(4-nitro-phenyl)-oxazole (400 mg, 2.1 mmol) in methanol (10 ml) was hydrogenated over 10% Pd/C at 30 psi until no further gas uptake was observed. The reaction mixture was then filtered over celite and concentrated to give a residue which was purified by column chromatography using ethyl acetate/pet ether (3:7) to yield 4-oxazol-2-yl-phenylamine (300 mg, 89%).
