Versuchsvorschrift

A resealable reaction tube was charged with 1,4-dichloro-5,6,7,8-tetrahydrophthalazine (0.050 g, 0.246 mmol), 4-(2-(4-aminophenoxy)pyridin-3-yl)-N-methylpyrimidin-2-amine (0.072 g, 0.246 mmol), tris(dibenzylideneacetone)dipalladium (0)(0.011 g, 0.012 mmol), 2-dicyclohexylphosphino-2′,6′-dimethoxy-1,1′-biphenyl (0.020 g, 0.049 mmol), and sodium tert-butoxide (0.033 g, 0.345 mmol). The vial was purged with nitrogen for several minutes, followed by addition of 0.50 mL of toluene. The vial was capped and heated to 150° C. for 16 h. The reaction mixture was allowed to cool and was filtered through a plug of Celite, rinsing with dichloromethane. The filtrate was concentrated, and the crude material was purified by reverse phase chromatography, Gilson, 5-95% acetonitrile/H2O/0.1% TFA over 14 min. The product-containing fractions were combined, brought to basic pH by addition of 2M Na2CO3 and extracted with dichloromethane. The organic portion was dried with MgSO4, filtered, and concentrated to give 4-chloro-N-(4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)-5,6,7,8-tetrahydrophthalazin-1-amine as a light brown solid. MS m/z=460 [M+H]+. Calc'd for C24H22ClN7O: 459.93.
