Procedure
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), a 2 M solution of ethylamine in THF (0.065 mL, 0.129 mmol), and NaCNBH3 (16 mg, 0.258 mmol) were reacted to give 19 mg of crude ethyl{[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methyl}amine. The crude 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(II) (4.4 mg, 0.00723 mmol) to give 12.3 mg of the title compound (36%).
