PROCEDURE
实验过程
To a degassed solution of 2,6-dichloronicotinaldehyde (315 mg, 1.79 mmol) and 2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzofuran-3-carboxamide (600 mg, 1.19 mmol) in 1,4-dioxane (8 mL) and water (300 μL) was added K2CO3 (330 mg, 2.40 mmol) and Pd(dppf)Cl2 (175 mg, 0.24 mmol) under N2 protection. The resulting mixture was heated to 80° C. and stirred at this temperature overnight. The reaction was cooled, filtered through a pad of celite and washed with ethyl acetate. The combined filtrate was evaporated in vacuo. The resulting residue was purified using column chromatography (eluted with 0-30% EtOAc/DCM) to provide 5-(6-chloro-5-formylpyridin-2-yl)-2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (530 mg, yield: 86%) MS (M+H)+: 516.
