실험 절차

Following the general procedure of 5-(5-{[(cyclopropylmethyl)amino]methyl}-3-pyridinyl)-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide, 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinecarbaldehyde (30 mg, 0.129 mmol), [2-(methyloxy)ethyl]amine (0.011 mL, 0.129 mmol), and NaCNBH3 (16 mg, 0.258 mmol) were reacted to give 19 mg of crude [2-(methyloxy)ethyl]{[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methyl}amine. The crude [2-(methyloxy)ethyl]{[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methyl}amine was then reacted with 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (30 mg, 0.0723 mmol), potassium carbonate (60 mg, 0.434 mmol), and chloro-2-(dimethylaminomethyl)-ferrocen-1-yl-(dinorbornylphosphine)palladium(11) (4.4 mg, 0.00723 mmol) to give 15 mg of the title compound (46%).
