Procedure

Following the general procedure of 5-(5-{[(2-ethylbutyl)amino]methyl}-2-thienyl)-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide, (5-formyl-2-thienyl)boronic acid (50 mg, 0.32 mmol), hexylamine (33 mg, 0.32 mmol), and NaCNBH3 (40 mg, 0.64 mmol) were reacted to give 30 mg of crude {5-[(hexylamino)methyl]-2-thienyl}boronic acid. The crude {5-[(hexylamino)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) (9 mg, 0.0079 mmol). The crude product was purified once on an Agilent MDAP using the procedure shown in preparation of 5-(5-{[(2-ethylbutyl)amino]methyl}-2-thienyl)-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide to give 13 mg of the title compound (16%).
