Procedure

Following the general procedure of 5-{5-[(ethylamino)methyl]-2-thienyl}-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide, (5-formyl-2-thienyl)boronic acid (50 mg, 0.32 mmol), (2,2-dimethylpropyl)amine (0.037 mL, 0.32 mmol), and NaCNBH3 (40 mg, 0.64 mmol) were reacted to give 73 mg of crude (5-{[(2,2-dimethylpropyl)amino]methyl}-2-thienyl)boronic acid. The crude (5-{[(2,2-dimethylpropyl)amino]methyl}-2-thienyl)boronic acid was then reacted with 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (80 mg, 0.193 mmol), potassium carbonate (160 mg, 1.16 mmol), and tetrakis(triphenylphosphine)palladium(0) (5 mg, 0.004 mmol) to give 21 mg of the title compound (21%).
