실험 절차

To a sealed tube were added N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(6-chloro-5-methylpyridin-3-yl)acetamide 148-1 (123 mg, 0.32 mmol), 2-(trifluoromethyl)pyridin-4-ylboronic acid (61 mg, 0.32 mmol), Pd(OAc)2 (3.6 mg, 0.016 mmol), 2,6-Dimethoxy-1,1′-biphenyl-2-yl)dicyclohexylphosphine (13.0 mg, 0.032 mmol) and K3PO4 (202 mg, 0.95 mmol). The tube and its contents were then purged with nitrogen. After degassed toluene (1.0 mL) was added, the mixture was stirred at 120° C. overnight. After cooling to room temperature, the mixture was poured into water and extracted with ethyl acetate (8 mL×3). The combined organic phases were dried over Na2SO4, and concentrated. The residue was purified by reverse phase HPLC to give to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(3-methyl-2′-(trifluoromethyl)-2,4′-bipyridin-5-yl)acetamide 222.
