A solution of dichlorobis(triphenylphosphine)palladium(ii) (19.5 mg, 0.028 mmol), sodium carbonate (88 mg, 0.83 mmol), 2-amino-4-chloropyrimidine (35.9 mg, 0.28 mmol), 5-(5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-ylamino)-6-morpholinopyridin-3-ylboronic acid (0.28 mmol; described herein), 1,4-dioxane (6 mL), and water (1.5 mL) was heated in a microwave at 120° C. for 60 min. The reaction was then partitioned between EtOAc and water, and the organic layer dried (magnesium sulfate) and concentrated. Chromatography afforded N-(5-(2-amino-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 8.73-8.79 (1H, m), 8.58 (1H, d, J=2.3 Hz), 8.28 (1H, d, J=5.1 Hz), 7.85-7.96 (2H, m), 7.63-7.70 (1H, m), 7.48-7.59 (2H, m), 7.41 (1H, ddd, J=6.8, 4.7, 2.2 Hz), 6.98-7.10 (2H, m), 5.35 (2H, br. s.), 3.95 (4H, d, J=2.3 Hz), 3.10-3.70 (4H, m), 2.22 (3H, s).
