Procedure

7-Chloro-5-(isopropylamino)-3-methylpyrido[4,3-d]pyrimidin-4(3H)-one (60 mg, 0.24 mmol), crude 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-(methylsulfonyl)-N-(2-morpholinoethyl)benzenamine (240 mg, ˜0.28 mmol), Pd(PPh3)4 (28 mg, 0.024 mmol) and Na2CO3 (102 mg, 0.96 mol) in a mixed solvent of acetonitrile (4 mL) and H2O (4 mL) were added to a 20 mL microwave tube and sealed. The tube was then heated in a Microwave Reactor at 140° C. for 10 minutes. The solvent was removed and the crude product purified by silica column using 7% MeOH in DCM to give the final product as a pale solid. ESI-MS m/z 501.2 (MH+); 1H NMR (DMSO-d6) δ 8.71 (d, J=7.2 Hz, 1H), 8.46 (d, J=2.4 HZ, 1H), 8.40 (s, 1H), 8.26 (d, J=8.8 Hz, 1H), 7.04 (s, 1H), 6.97 (d, J=8.8 Hz, 1H), 6.77 (t, J=4.8 Hz, 1H), 3.59 (m, 4H), 3.42 (s, 3H), 3.33 (m, 4H), 3.20 (s, 3H), 2.62 (m, 2H), 2.44 (s, 3H), 1.29 (d, J=6.4 Hz, 6H).
