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), {3-[(1-methylethyl)oxy]propyl}amine (38 mg, 0.32 mmol), and NaCNBH3 (40 mg, 0.64 mmol) were reacted to give 30 mg of crude {5-[({3-[(1-methylethyl)oxy]propyl}amino)methyl]-2-thienyl}boronic acid. The crude {5-[({3-[(1-methylethyl)oxy]propyl}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) (9 mg, 0.0079 mmol). After purification on an Agilent MDAP twice as shown in preparation of 5-(5-{[(2-ethylbutyl)amino]methyl}-2-thienyl)-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide, the impure title compound was washed with a 20:4:1 mixture of hexanes/EtOAc/MeOH (2.5 mL) to give 7.6 mg of the title compound (9%).
