Reaction Steps

3-bromo-N-(5-(2,6-difluorobenzyl)-1-methylpiperidin-3-yl)-1-trityl-1H-indazole-5-carboxamide (0.050 g, 0.0716 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]-dichloropalladium(II) (0.0052 g, 0.00716 mmol), Potassium phosphate tribasic (0.046 g, 0.215 mmol) and 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.018 g, 0.0788 mmol) was added into a flask. After purging the reaction vessel with nitrogen gas, dioxane (0.215 mL) and water (0.043 mL) was added. The reaction was allowed to stir at 80° C. for 16 hrs. The reaction was quenched with water (1 mL) and extracted with dichloromethane (3×1 mL). The extracts were combined, dried using sodium sulfate, filtered through celite, and concentrated under vacuo. The crude product was progressed to the next step without further purification. LC-MS found 718.2, calcd M+H 718.3.
