Procedure

A solution of 6-bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-isopropyl-1H-indazole-4-carboxamide (0.30 g, 0.72 mmol), 4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl)morpholine (0.26 g, 0.865 mmol) and Pd(PPh3)4 (0.042 g, 0.036 mmol) in 1,4-dioxane (6 mL) was purged with argon for 10 min. 2M Na2CO3 solution (0.27 g, 2.54 mmol) was then added before an additional argon purged for 10 min. The reaction mixture was stirred at 80° C. for 2 h. After completion of the reaction, water was added to it and extraction was carried out using EtOAc. 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 corresponding N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-isopropyl-6-(4-(morpholinomethyl)phenyl)-1H-indazole-4-carboxamide (0.20 g, 55.7%).
