Reaction Steps

To a stirred solution of 4-methoxy-2-(pyridin-2-yl)pyrido[2,3-d]pyrimidine (0.050 g, 0.21 mmol) and 2,5-dimorpholinopyridin-3-amine (0.061 g, 0.23 mmol) in N,N-dimethylformamide (2.0 mL) was added 60% sodium hydride (9.23 mg, 0.23 mmol). The reaction was heated to 60° C. Stirring continued overnight. The reaction was cooled to rt and water was added to quench. The reaction was extracted with EtOAc (3×10 mL). The combined organic layer were dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel (0 to 30% MeOH in DCM) to give N-(2,5-di-4-morpholinyl-3-pyridinyl)-2-(2-pyridinyl)pyrido[2,3-d]pyrimidin-4-amine. 1H NMR (400 MHz, CDCl3) δ ppm 9.75 (1H, d, J=2.7 Hz), 9.36 (1H, br. s.), 9.23 (1H, dd, J=4.4, 1.7 Hz), 8.87 (1H, d, J=8.0 Hz), 8.70 (1H, m), 8.30 (1H, dd, J=8.2, 1.8 Hz), 7.91 (1H, m), 7.84 (1H, d, J=2.7 Hz), 7.62 (1H, dd, J=8.2, 4.3 Hz), 7.42-7.49 (1H, m), 3.94-4.04 (8H, m), 3.43-3.55 (4H, br m), 3.09 (4H, br. m.). Mass Spectrum (ESI) m/e=471.3 (M+1).
