실험 절차

A mixture of 6-chloro-N-(6-methoxypyridin-3-yl)pyrido[3,2-d]pyrimidin-4-amine (Intermediate 22) (0.040 g, 0.139 mmol), N-(2-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-3-yl)-2,4-difluorobenzenesulfonamide (Intermediate 3) (0.066 g, 0.153 mmol), PdCl2(dppf)-CH2Cl2Adduct (0.011 g, 0.014 mmol) and 1 N aq. sodium bicarbonate (0.278 ml, 0.278 mmol) in dioxane (1.40 ml) subjected to microwave irradiation for 1 hour at 110° C. After cooling to room temperature, the reaction mixture was filtered through Celite and washed with CH2Cl2. The filtrate was concentrated in vacuo. The residue was purified by column chromatography on SiO2 (Hex:EtOAc=1:1) to give N-(2-chloro-5-(4-(6-methoxypyridin-3-ylamino)pyrido[3,2-d]pyrimidin-6-yl)pyridin-3-yl)-2,4-difluorobenzenesulfonamide (0.024 g, 31%) as a yellow solid. 1H-NMR (DMSO-d6, Varian 400 MHz) δ 3.89 (3H, s), 6.94 (3H, s), 6.89-7.05 (1H, d, J=8.4 Hz), 7.17-7.28 (1H, m), 7.50-7.65 (1H, m), 7.74-7.86 (1H, m), 8.17 (1H, dd, J=2.4, 8.8 Hz), 8.33 (1H, d, J=8.8 Hz), 8.36 (1H, d, J=8.8 Hz), 8.57 (1H, d, J=8.8 Hz), 8.62 (2H, s), 8.82 (1H, s), 9.48 (1H, s), 10.33 (1H, s), 10.98 (1H, br s). m/z=556.2 [M+1]+.
