Reaction Steps

3-(4-aminopyrido[3,2-d]pyrimidin-6-yl)-5-fluoro-benzoic acid (100 mg, 0.35 mmol) 3 in DMF was treated with DIPEA (0.3 mL, 1.76 mmol) followed by HATU (279 mg, 0.7 mmol). The mixture was stirred at room temperature for 10 minutes, then 2-amino-2-methyl-propan-1-ol, (CAS-124-68-5) (0.07 mL, 0.7 mmol) was added and continue stirred at room temperature overnight. Saturated sodium bicarbonate was added, and the mixture was extracted with EtOAc. The combined organics were dried over sodium sulfate and concentrated. The crude was purified by Prep HPLC to give 15 mg of 3-(4-aminopyrido[3,2-d]pyrimidin-6-yl)-5-fluoro-N-(1-hydroxy-2-methylpropan-2-yl)benzamide 4. LC/MS (ESI+): m/z 356 (M+H). 1H NMR (400 MHz, DMSO) δ 8.55 (t, J=8.7 Hz, 1H), 8.47 (s, 1H), 8.44 (d, J=7.1 Hz, 1H), 8.18 (t, J=8.8 Hz, 1H), 7.82 (d, J=24.4 Hz, 1H), 7.71 (d, J=9.4 Hz, 1H), 4.87 (t, J=6.0 Hz, 1H), 3.58 (d, J=5.8 Hz, 2H), 2.07 (s, 2H), 1.36 (s, 6H).
