Iron powder (55 mg) was added to 4.5 ml of a methanol:water:acetic acid=1:1:1 mixed solvent solution containing 38 mg of 5-{[2-fluoro-5-methoxy-3-(2-methoxyethoxy)phenyl]-[4-(5-trifluoromethyl-[1,2,4]oxadiazol-3-yl)phenylamino]methyl}-2-(3-nitropyridin-2-yl)-2,4-dihydro-[1,2,4]triazol-3-one. The mixture was stirred at 65° C. for 24 hours under a nitrogen atmosphere. The reaction mixture was filtered and then purified by reverse-phase high performance liquid chromatography (acetonitrile-water, 0.1% acetic acid) to give the title compound (25 mg).
