Reaction Steps

To a solution of [6-chloro-5-(4-trifluoromethylphenyl)pyridazin-3-yl]-[quinolin-7-yl]amine, Example 88, (100 mg, 0.3 mmol) in dioxane (2 mL) was added 4-methoxyphenylboronic acid (46 mg, 0.3 mmol, Aldrich), followed by the addition of 2M aq Na2CO3 (0.2 mL, 0.4 mmol) and Pd[PPh3]4 (35 mg, 0.03 mmol, Aldrich). The mixture was flushed with N2 and heated under at 100° C. under N2 atmosphere for 24 h. The reaction mixture was cooled to room temperature, additional amounts of 2M aq Na2CO3 (0.2 mL, 0.4 mmol), 4-methoxyphenyl-boronic acid (46 mg, 0.3 mmol) and Pd[PPh3]4 (35 mg, 0.03 mmol) were added and the mixture was heated at 100° C. with stirring under N2 atmosphere for 4 h. The reaction mixture was cooled to room temperature, diluted with EtOAc (50 mL) and washed with 5% Na2CO3. The organic layer was dried over Na2SO4, filtered and the solvent evaporated in vacuo. The residue was purified by column chromatography, eluting with MeOH:CH2Cl2 (1:19), to give the title compound as a tan crystalline solid. MS (ESI, pos. ion) m/z: 473 (M+1). MP: 215-217° C.
