Procedure

Following the same reaction and purification procedure, the acid 14 (50 mg, 0.18 mmol) was reacted with methyl amine 2M in THF (0.18 mL, 0.35 mmol), HATU (103 mg, 0.6 mmol) and DIPEA (0.15 mL, 0.88 mmol) in DMF (1 mL) at room temperature to provide 3-(4-aminopyrido[3,2-d]pyrimidin-6-yl)-N-methylbenzamide 20. LC/MS (ESI+): m/z 280 (M+H). 1H NMR (400 MHz, DMSO) δ 8.76 (s, 1H), 8.59 (dd, J=10.4, 6.2 Hz, 2H), 8.49 (d, J=8.9 Hz, 1H), 8.43 (d, J=5.3 Hz, 1H), 8.18 (d, J=8.8 Hz, 1H), 8.07 (d, J=17.7 Hz, 2H), 7.96 (d, J=7.7 Hz, 1H), 7.63 (t, J=7.8 Hz, 1H), 2.83 (t, J=24.6 Hz, 3H).
