실험 절차

To a solution of N-(5-(4-(piperidin-4-yloxy)pyrido[3,2-d]pyrimidin-6-yl)pyridin-3-yl)benzene-sulfonamide (0.082 g, 0.177 mmol) in DCM (0.886 ml) was added TEA (0.062 ml, 0.443 mmol) at room temperature. After stirring for 2 hours at room temperature, AcCl (0.019 ml, 0.266 mmol) was added to the mixture at 0° C. After stirring overnight at room temperature, the reaction mixture was diluted with water and extracted with CH2Cl2. The combined organic layers were washed with brine, dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by prep TLC (DCM:MeOH=20:1) to give N-(5-(4-(1-acetylpiperidin-4-yloxy)-pyrido[3,2-d]pyrimidin-6-yl)pyridin-3-yl)benzenesulfonamide (0.007 g, 7%) as a white solid. 1H-NMR (CDCl3, Varian 400 MHz) δ 2.05-2.18 (2H, m), 2.19 (3H, s), 3.53-3.59 (2H, m), 3.65-3.76 (2H, m), 3.89-3.40 (2H, m), 5.74-8.79 (1H, m), 7.44-7.48 (2H, m), 7.53-7.57 (1H, m), 7.86-7.89 (2H, m), 8.23 (1H, d, J=8.8 Hz), 8.36 (1H, d, J=8.8 Hz), 8.46 (1H, d, J=2.8 Hz), 8.53 (1H, d, J=2.4 Hz), 8.84 (1H, s), 9.12 (1H, d, J=1.6 Hz). m/z=505.1 [M+1]+.
