Versuchsvorschrift

To a mixture of 2-methoxy-4-(4-methylpiperazin-1-yl)aniline (Combi-Blocks Inc, Cat#: SS-3744; 342 mg, 1.55 mmol) and tert-butyl (3-(2-(methylsulfinyl)-7-oxopyrido[2,3-d]pyrimidin-8(7H)-yl)phenyl)carbamate (52) (521 mg, 1.30 mmol) in tert-butanol (10 mL, 105 mmol) was added DIEA (0.57 mL, 3.25 mmol). The reaction mixture was heated at 80° C. in an oil bath for 21 h. The resulting brown suspension was concentrated under reduced pressure and the crude solid was suspended in Et2O (ca. 20 mL) and filtered affording the crude material of tert-butyl (3-(2-((2-methoxy-4-(4-methylpiperazin-1-yl)phenyl)amino)-7-oxopyrido[2,3-d]pyrimidin-8(7H)-yl)phenyl)carbamate (1a) as a green solid. m/z (ESI, +ve ion) 558.0 (M+H)+. 1H NMR (400 MHz, DMSO-d6) δ ppm 9.57 (1H, s), 8.73 (1H, s), 8.14 (1H, s), 7.89 (1H, d, J=9.4 Hz), 7.57 (1H, d, J=8.4 Hz), 7.42 (3H, t, J=8.0 Hz), 7.28 (1H, d, J=8.8 Hz), 6.87 (1H, d, J=8.6 Hz), 6.53 (1H, d, J=2.3 Hz), 6.43 (1H, d, J=9.4 Hz), 6.05 (1H, br. s.), 3.73-3.82 (3H, m), 3.06 (4H, br. s.), 2.36-2.47 (4H, 2.15-2.26 (3H, s), 1.45 (9H, s).
