PROCEDURE
实验过程
A solution of 6-bromo-1-cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1H-indazole-4-carboxamide (0.1 g, 0.2 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinaldehyde (0.064 g, 0.274 mmol) and Pd(PPh3)4 (0.013 g, 0.011 mmol) in 1,4-dioxane (2 mL) was purged with argon for 10 min. A solution of 2M Na2CO3 (0.087 g, 0.820 mmol) was then added to it and argon again purged for 10 min. The reaction mixture was stirred at 100° C. for 1 h. After completion of the reaction, water was added and extraction was carried out using ethyl acetate. The combined organic layers were washed with water, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to afford crude material which was purified by column chromatography to give 1-cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-6-(6-formylpyridin-3-yl)-1H-indazole-4-carboxamide (0.1 g, 94.3%).
