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-(propyloxy)propyl]amine (38 mg, 0.32 mmol), and NaCNBH3 (40 mg, 0.64 mmol) were reacted to give 30 mg of crude [5-({[3-(propyloxy)propyl]amino}methyl)-2-thienyl]boronic acid. The crude [5-({[3-(propyloxy)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). The crude product was purified twice 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. The purified product was washed with a 20:4:1 mixture of hexanes/EtOAc/MeOH (2.5 mL), taken up in EtOAc (2 mL) and washed with saturated K2CO3 (1 mL). The organic layer was concentrated to give to give 1.4 mg of the title compound (2%).
