실험 절차

To a degassed solution of 2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)-5-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)benzofuran-3-carboxamide (117 mg, 0.23 mmol) and 2-chloro-6H-benzo[e]benzo[4,5]imidazo[1,2-c][1,3]oxazine (60 mg, 0.23 mmol) in dioxane:H2O (2 mL:0.5 mL) was added Pd2(dba)3 (21 mg, 0.02 mmol), X-Phos (22 mg, 0.05 mmol) and K3PO4 (184 mg, 0.69 mmol) under N2. The mixture was heated to 100° C. and stirred for about 15 hours. The reaction mixture was cooled to room temperature and filtered. The filtrate was washed with H2O, brine, dried over Na2SO4. After being concentrated in vacuo, the resulting resulting residue was purified using prep-HPLC to provide the product of Compound 133 (30 mg, yield: 22%). 1H-NMR (DMSO-d6, 400 MHz) δ 8.59 (d, J=4.4 Hz, 1H), 8.14 (d, J=1.9 Hz, 1H), 8.08˜8.05 (m, 3H), 7.77˜7.72 (m, 2H), 7.69 (s, 1H), 7.63 (dd, J=8.7, 2.0 Hz, 1H), 7.46 (t, J=8.7 Hz, 2H), 7.37˜7.30 (m, 3H), 6.38 (s, 2H), 3.21 (s, 3H), 3.05 (s, 3H), 2.87 (d, J=4.4 Hz, 3H). MS (M+H)+: 597.
