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), 2-methylpyrrolidine (0.013 mL, 0.129 mmol), and NaCNBH3 (16 mg, 0.258 mmol) were reacted to give 25 mg of crude 3-[(2-methyl-1-pyrrolidinyl)methyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine. The crude 3-[(2-methyl-1-pyrrolidinyl)methyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine 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 6 mg of the title compound (16%).
