実験手順

In a nitrogen purged sealed tube was added 1,4-dioxane (1.35 mL), and the solution was purged with nitrogen for 5 minutes, then sealed. 1-Methyl-2-(tributylstannyl)-1H-imidazole (0.311 g, 0.837 mmol), 4-chloro-N-(4-(7-methoxy-1,5-naphthyridin-4-yloxy)phenyl)phthalazin-1-amine (0.120 g, 0.279 mmol) were added to the tube, which was then purged with nitrogen and sealed. To the tube was added 1,1′-bis(diphenylphosphino)ferrocene-palladium dichloride (0.102 mg, 0.140 mmol), and the tube was purged with nitrogen, sealed, and heated to 100° C., while stirring the reaction for 17 hours. The reaction was cooled to RT, and concentrated. The concentrate was purified using reverse phase chromatography, the product fractions were concentrated, extracted into DCM, washed once with sodium carbonate and once with water, upon which the title compound precipiated. The solids were filtered, washed with water, air dried to yield N-(4-(7-methoxy-1,5-naphthyridin-4-yloxy)phenyl)-4-(1-methyl-1H-imidazol-2-yl)phthalazin-1-amine (0.039 g) as light yellow solid. MS [M+H]=476.0; Calc'd 475.5 for C27H21N7O2.
