実験手順
A mixture of N-[(1S)-1-(3-aminophenyl)ethyl]-6-bromopyridin-2-amine (70 mg, 0.24 mmol), 5-methylnicotinic acid (39 mg, 0.29 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (69 mg, 0.36 mmol), 4-pyrrolidinopyridine (7 mg, 0.05 mmol) and triethylamine (0.08 mL, 0.58 mmol) in dichloromethane (3 mL) was stirred at room temperature for 17 hours. After this time the mixture was diluted with dichloromethane (20 mL), washed successively with saturated aqueous sodium hydrogen carbonate (2×15 mL) and brine (15 mL), dried (Na2SO4) and concentrated under reduced pressure to give a dark yellow oil which was purified by flash chromatography (silica, ethyl acetate/hexanes) to give N-(3-{(1S)-1-[(6-bromopyridin-2-yl)amino]ethyl}phenyl)-5-methylnicotinamide (62 mg, 63%) as a pale yellow foam.
