실험 절차

To 9-Bromo-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene from Example 6 (0.388 g, 0.992 mmol), 2-methylpyridin-3-ylboronic acid (0.176 g, 1.29 mmol), potassium acetate (0.389 g, 3.96 mmol), and tetrakis(triphenylphosphine)palladium(0) (57 mg, 0.049 mmol) was added DMF (20 mL) and water (1 mL). Nitrogen was bubbled through the reaction mixture for 5 minutes. The reaction mixture was allowed to stir at 105° C. for 24 hours before cooling, diluting with EtOAc, and filtering through a pad of celite. The filtrate was concentrated under reduced pressure and diluted with EtOAc. The solution was washed sequentially with water, and brine, before drying over MgSO4 and concentrating under reduced pressure. The crude material was dissolved in DMF and purified by reverse phase HPLC to provide 128 (115 mg, 28%). 1H NMR (400 MHz, DMSO) δ 8.44 (dd, J=24.8, 2.7, 2H), 8.10 (s, 1H), 7.69 (t, J=8.1, 1H), 7.35 (ddd, J=12.5, 7.9, 3.6, 2H), 7.19 (d, J=8.3, 1H), 5.74 (dt, J=13.2, 6.7, 1H), 4.44 (t, J=4.9, 2H), 3.49 (t, J=4.9, 2H), 2.53 (s, 3H), 1.48 (d, J=6.6, 6H). MS (ESI(+)): m/z 404.1 (M+H).
