Procedure

Following the general procedure of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(5-{[(2-methylbutyl)amino]methyl}-2-thienyl)-1H-indole-7-carboxamide, (5-formyl-2-thienyl)boronic acid (50 mg, 0.32 mmol), (3-methylbutyl)amine (28 mg, 0.32 mmol), and NaCNBH3 (40 mg, 0.64 mmol) were reacted to give 46 mg of crude (5-{[(3-methylbutyl)amino]methyl}-2-thienyl)boronic acid. The crude (5-{[(3-methylbutyl)amino]methyl}-2-thienyl)boronic acid was then reacted with 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (65 mg, 0.157 mmol), K2CO3 (130 mg, 0.942 mmol), and tetrakis(triphenylphosphine)palladium(0) (4 mg, 0.003 mmol) to give 38.3 mg of the title compound (37%).
