Prepared according to Procedure K, method 2 using 2,5-dimorpholinopyridin-3-amine (143 mg, 0.543 mmol; described herein), 4-chloro-7-fluoro-3-methyl-2-(pyridin-2-yl)quinoline (148 mg, 0.54 mmol; described herein), 4.0M hydrochloric acid in 1,4-dioxane (140 μL, 0.54 mmol), and NMP (780 μL, 8.1 mmol). The reaction was heated in a microwave at 160° C. for three h. Purification afforded N-(2,5-di-4-morpholinyl-3-pyridinyl)-7-fluoro-3-methyl-2-(2-pyridinyl)-4-quinolinamine as a yellow solid. 1H NMR (400 MHz, chloroform-d) δ ppm 8.75 (1H, dd, J=4.3, 0.8 Hz), 7.93 (3H, d, J=5.5 Hz), 7.86 (1H, br. s.), 7.60-7.69 (1H, m), 7.38-7.46 (1H, m), 7.29-7.36 (2H, m), 6.31 (1H, br. s.), 3.91 (4H, br. s.), 3.68-3.81 (4H, m), 3.25 (4H, br. s.), 2.95 (4H, br. s.), 2.38 (3H, s). Mass Spectrum (ESI) m/e=501.2 (M+1).
