実験手順

To phenylboronic acid (0.030 g, 0.24 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium dichloride (0.0060 g, 0.0081 mmol) and 4-chloro-5,8-difluoro-N-(4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)phthalazin-1-amine (0.080 g, 0.16 mmol) was added dioxane (0.35 mL) and sodium carbonate (2.0 M, aqueous) (0.16 ml, 0.33 mmol). The resulting mixture was heated to 85° C. in a sealed tube for 60 minutes. The reaction was diluted with EtOAc and water, and the layers were separated and the organic layers were dried over sodium sulfate, filtered and concentrated. The crude was purified by ISCO silica gel chromatography (20-100% EtOAc/hexanes; 40 g column). Concentrated product fractions to yield 5,8-difluoro-N-(4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)-4-phenylphthalazin-1-amine as an off-white solid. MS m/z=534 [M+H]+. Calc'd for C30H21F2N7O: 533.54.
