Procedure

Following the same reaction and purification procedure, the acid 3 (100 mg, 0.35 mmol) was reacted with 2-aminoethanol (CAS 141-43-5) (43 mg, 0.7 mmol), HATU (276 mg, 0.7 mmol) and DIPEA (0.30 mL, 1.8 mmol) in DMF (1 mL) at room temperature to provide 3-(4-aminopyrido[3,2-d]pyrimidin-6-yl)-5-fluoro-N-(2-hydroxyethyl)benzamide 7. LC/MS (ESI+): m/z 328 (M+H).
