After adding 1.2 g of iron powder to a solution of 1.2 g of 5-{[2-fluoro-3-(2-fluoroethoxy)-5-methoxyphenyl]-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamino]methyl}-2-pyrimidin-2-yl-2,4-dihydro-[1,2,4]triazol-3-one in 18 ml of a methanol:water:acetic acid=1:1:1 mixed solvent, the mixture was stirred at 65° C. for 24 hours and 30 minutes under a nitrogen atmosphere. After filtering the reaction mixture, it was purified by reverse-phase high performance liquid chromatography (acetonitrile-water, 0.1% acetic acid) to give the title compound (750 mg) as a light yellow solid.
