Reaction Steps

After adding 13 mg of 2-hydrazinopyrimidine and 0.016 ml of triethylamine to a solution of 69 mg of (2-{2-fluoro-5-methoxy-3-[2-(tetrahydropyran-2-yloxy)ethoxy]phenyl}-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene)carbamic acid methyl ester in 1 ml of DMF, the mixture was stirred at 85° C. for 16 hours under a nitrogen atmosphere. The reaction mixture was concentrated to give a crude product of 5-({2-fluoro-5-methoxy-3-[2-(tetrahydropyran-2-yloxy)ethoxy]phenyl}-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]methyl)-2-pyrimidin-2-yl-2,4-dihydro-[1,2,4]triazol-3-one.
