Reaction Steps

A solution of 5-(5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-ylamino)-6-morpholinopyridin-3-ylboronic acid (0.026 mmol, described herein), 4-chloro-6-methylpyrimidin-2-amine (3.7 mg, 0.026 mmol), sodium carbonate (8.18 mg, 0.077 mmol), dichlorobis(triphenylphosphine)palladium(ii) (1.8 mg, 2.57 μmol), 1,4-dioxane (560 μL) and water (140 μL) heated in a microwave at 120° C. for 60 min. The reaction was then cooled to rt and partitioned between EtOAc and water. The organic layer was dried (magnesium sulfate) and concentrated, and chromatography afforded N-(5-(2-amino-6-methyl-4-pyrimidinyl)-2-(4-morpholinyl)-3-pyridinyl)-5,7-difluoro-3-methyl-2-(2-pyridinyl)-4-quinolinamine as a yellow solid. 1H NMR (400 MHz, chloroform-d) δ ppm 8.72-8.81 (1H, m), 8.52-8.61 (1H, m), 7.85-7.96 (2H, m), 7.61-7.71 (1H, m), 7.52-7.61 (1H, m), 7.47-7.52 (1H, m), 7.41 (1H, m), 7.03 (1H, m), 6.84-6.93 (1H, m), 5.22 (2H, br. s.), 3.94 (4H, br. s.), 3.45-3.73 (2H, m), 3.00-3.40 (2H, br. s.), 2.33-2.52 (3H, m), 2.15-2.29 (3H, m). Mass Spectrum (ESI) m/e=541.0 (M+1).
