実験手順

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 (452 mg, 0.90 mmol) and compound (2-(3-(benzyloxy)-6-chloropyridin-2-yl)pyrazolo[1,5-a]pyridin-3-yl)methanol (300 mg, 0.82 mmol) in dioxane/H2O (5 mL/1 mL) was added Pd2(dba)3 (90 mg, 0.1 mmol), X-Phos (95 mg, 0.2 mmol) and K3PO4 (1.2 g, 2.4 mmol) under N2. After stirred at 100° C. overnight, the reaction mixture was cooled to room temperature and filtered. The filtrate was washed with brine and dried over Na2SO4. After concentrated, the resulting residue was purified using column chromatography (petroleum ether:ethyl acetate=1:2) to provide the product of compound 5-(5-(benzyloxy)-6-(3-(hydroxymethyl)pyrazolo[1,5-a]pyridin-2-yl)pyridin-2-yl)-2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (300 mg, yield: 53%). 1H-NMR (Methanol-d4, 400 MHz) δ 8.47 (d, J=8.8 Hz, 1H), 8.00 (dd, J=5.2, 8.8 Hz, 2H), 7.76 (d, J=8.8 Hz, 1H), 7.68 (d, J=9.2 Hz, 1H), 7.63 (d, J=8.4 Hz, 1H), 7.30˜7.24 (m, 7H), 7.16˜7.11 (m, 1H), 7.13 (dt, J=0.8, 6.8 Hz, 1H), 5.22 (s, 2H), 4.74 (s, 2H), 3.29 (s, 3H), 2.93 (s, 3H), 2.89 (s, 3H).
