Compound 95, methanesulfonic acid 2-{4-[N′-(3-methyl-benzylidene)-hydrazino]-6-morpholin-4-yl-pyrimidin-2-yl}-ethyl ester (50 mg., 0.12 mmol) was dissolved in tetrahydrofuran (2 mL). To the reaction mixture was added 5-pyridin-4-yl-4H-[1,2,4]triazole-3-thiol (124 mg., 0.66 mmol) and sodium hydride (12 mg., 0.5 mmol) and the vessel was stirred at room temperature for sixteen hours. The solvent was removed under reduced pressure and the crude oil was purified by column chromatography to give Compound 25, N-(3-methyl-benzylidene)-N′-{6-morpholin-4-yl-2-[2-(5-pyridin-4-yl-4H-[1,2,4]triazol-3-ylsulfanyl)-ethyl]-pyrimidin-4-yl}-hydrazine (34 mg.).
