Reaction Steps

To a solution of 70 mg of 5-{(3-ethoxy-4-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 3 ml of a methanol:water:acetic acid=1:1:1 mixed solvent there was added 70 mg of iron powder, and the mixture was stirred at 60° C. for 14 hours 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 41 mg of the title compound.
