Reaction Steps

The title compound was prepared according to a method described in Garnier, E.; Andoux, J.; Pasquinet, E.; Suzenet, F.; Poullain, D.; Lebret, B.; Guillaumet, G. J. Org. Chem. 2004, 69, 7809. Xantphos (22 mg, 39 μmol) and 1,4-Dioxane (963 μl, 193 μmol) were added into a sealed tube. The tube was purged with argon, Palladium(II) acetate (4 mg, 19 μmol) was added, and the mixture was stirred under argon for 10 min. In a separate sealed tube, N-(4-(6-bromoquinolin-4-yloxy)phenyl)-4-phenylphthalazin-1-amine (100 mg, 193 μmol), acetamide (57 mg, 963 μmol), potassium carbonate (798 mg, 5776 μmol), and 1,4-dioxane (963 μl, 193 μmol) were added. Then the Pd(OAc)2/Xantphos solution from the first tube was added with via syringe to the second tube. The resulting mixture was heated to 110° C. under an argon atmosphere with vigorous stirring until the halide disappeared. After 16 h, LCMS showed product at 1.324 as [M+H]+=498. The reaction was cooled to rt, quenched with water, extracted with CH2Cl2. The organic portions were combined, washed with brine, dried over MgSO4, filtered, and concentrated. The product was purified by RPLC on the acidic Gilson workstation. To provide N-(4-(4-(4-phenylphthalazin-1-ylamino)phenoxy)quinolin-6-yl)acetamide. MS Calcd for C31H23N5O2: [M]+=497. Found: [M+H]+=498.
