실험 절차

To a stirred solution of 6-bromo-N-((1,2-dihydro-6-methyl-2-oxo-4-propylpyridin-3-yl)methyl)-1-isopropyl-1H-indazole-4-carboxamide (0.2 g, 0.44 mmol) in DMF (10 mL) was added 4,4,5,5-tetramethyl-2-(thiophen-3-yl)-1,3,2-dioxaborolane (0.113 g, 0.53 mmol) followed by PdCl2(PPh3)2 (0.06 g, 0.08 mmol) and the reaction mixture was stirred for 5 min. Sodium carbonate (0.119 g, 0.940 mmol) dissolved in water (2 mL) was added and the contents were stirred at 120° C. for 3 h. The reaction mixture was diluted with NaHCO3 solution and extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine solution (20 mL), dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to afford the crude product. The crude product was purified by silica gel chromatography (eluent: 4% MeOH\EtOAc) to afford the title compound as an off white solid (75 mg, 38%). 1H NMR (DMSO-d6, 400 MHz): δ 0.883 (t, J=7.2 Hz, 3H), 1.491-1.550 (m, 8H), 2.13 (s, 3H), 2.501 (s, 2H), 4.419 (d, J=3.6 Hz, 2H), 5.130 (t, J=6.4 Hz, 1H), 5.912 (s, 1H), 7.691 (s, 1H), 7.766 (d, J=4.4 Hz, 1H), 7.930 (s, 1H), 8.041 (s, 1H), 8.171 (s, 1H), 8.353 (s, 1H), 8.563 (s, 1H), 11.530 (s, 1H). LCMS (ES+) m/z: 449.09.
