실험 절차

To a CEM microwave tube containing the crude (5-{[(2-methylbutyl)amino]methyl}-2-thienyl)boronic acid (43 mg, 0.188 mmol) was added 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (65 mg, 0.157 mmol), K2CO3 (130 mg, 0.942 mmol), dioxane (1.5 mL), H2O (0.5 mL) and tetrakis(triphenylphosphine)palladium(0) (4 mg, 0.003 mmol). The reaction was heated in a CEM microwave for 30 min at 150° C. The reaction mixture was filtered through a 2 g SCX cartridge (pre-equilibrated with 3 mL MeOH), eluting in sequence with H2O (3 mL), MeOH (9 mL) and a 2 M solution of NH3/MeOH (6 mL). The NH3/MeOH fraction was dried under a stream of nitrogen at 40° C., and the crude product was taken up in dimethyl sulfoxide (1 mL) and purified on an Agilent MDAP (Zorbax Eclipse XDB-C18 column: 21.2×50 mm) eluting at 20 mL per min for 1 min with 10% CH3CN/H2O (0.1% TFA) then a linear gradient of 10% CH3CN/H2O (0.1% TFA) to 95% CH3CN/H2O (0.1% TFA) over 8 min and holding at the final concentration for 30 sec. The fractions containing product were filtered through a 2 g Pharmasil CHQAX column (polymer bound ammonium hydroxide; United Chemical Technologies) to remove TFA and concentrated under a stream of nitrogen at 50° C. to give 16.2 mg of the title compound (17%).
