Procedure

Following the same reaction and purification procedure, the acid 14 (80 mg, 0.3 mmol) was reacted with 2-morpholinoethanamine (CAS 2038-03-1) (78 mg, 0.6 mmol), HATU (129 mg, 0.33 mmol) and DIPEA (0.26 mL, 1.5 mmol) in DMF (1 mL) at room temperature to provide 3-(4-aminopyrido[3,2-d]pyrimidin-6-yl)-N-(2-morpholinoethyl)benzamide 21. LC/MS (ESI+): m/z 379 (M+H). 1H NMR (400 MHz, DMSO) δ 8.73 (s, 1H), 8.60 (d, J=7.5 Hz, 2H), 8.50 (d, J=8.9 Hz, 1H), 8.43 (d, J=4.9 Hz, 1H), 8.19 (d, J=8.8 Hz, 1H), 8.06 (d, J=13.7 Hz, 2H), 7.96 (d, J=7.8 Hz, 1H), 7.64 (t, J=7.8 Hz, 1H), 3.67-3.53 (m, 4H), 3.47 (dd, J=13.2, 6.6 Hz, 2H), 2.53 (d, J=7.1 Hz, 2H), 2.48-2.40 (m, 4H).
