実験手順

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), [2-(methyloxy)ethyl]amine (24 mg, 0.32 mmol), and NaCNBH3 (40 mg, 0.64 mmol) were reacted to give 42 mg of crude [5-({[2-(methyloxy)ethyl]amino}methyl)-2-thienyl]boronic acid. The crude [5-({[2-(methyloxy)ethyl]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 impure title compound. The impure title compound was repurified using the HPLC and ammonium hydroxide SPE workup shown in preparation of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(5-{[(2-methylbutyl)amino]methyl}-2-thienyl)-1H-indole-7-carboxamide to give 15 mg of the title compound (15%).
