Procedure

To a stirred solution of dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (0.024 g, 0.050 mmol), 2,5-dimorpholinopyridin-3-amine (0.099 g, 0.37 mmol), 4-chloro-5,7-difluoro-2-(5-methoxypyridin-3-yl)-3-methylquinoline (0.10 g, 0.312 mmol) and Pd2dba3 (0.011 g, 0.012 mmol) in toluene (3.1 mL) was added sodium t-butoxide (0.075 g, 0.78 mmol). The reaction mixture was heated to 120° C. and stirring continued for 5 h. The reaction was cooled to rt and diluted with water (15 mL). The mixture was extracted with EtOAc (2×15 mL) and DCM (1×15 mL). The organic layers were combined and washed with brine (1×20 mL) and dried over magnesium sulfate. The crude product was purified by column chromatography on basic alumina (0 to 50% hexanes/EtOAc) to give the desired product N-(2,5-di(4-morpholinyl)-3-pyridinyl)-5,7-difluoro-2-(5-methoxy-3-pyridinyl)-3-methyl-4-quinolinamine. 1H NMR (400 MHz, CDCl3) δ ppm 8.43 (2H, t, J=2.1 Hz), 7.80 (1H, br. s.), 7.67 (1H, d, J=2.7 Hz), 7.49-7.54 (1H, m), 6.99-7.09 (1H, m), 6.38 (1H, br. s.), 3.97 (3H, s), 3.91 (4H, br. s.), 3.79-3.86 (4H, m), 3.21 (4H, br. s.), 3.00-3.09 (4H, m), 2.18 (3H, s). Mass Spectrum (ESI) m/e=549.3 (M+1).
