実験手順

A solution of 5-(2,5-difluorobenzyl)isoxazole-3-carboxylic acid (0.104 g, 0.435 mmol), 2-(5-bromo-1H-indol-3-yl)ethanamine hydrochloride (0.120 g; 0.435 mmol), HATU (0.166 g; 0.435 mmol) and N,N diisopropylethylamine (0.201 mL; 1.09 mmol) in DMF (5 mL), was stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and sodium hydrogen sulphate, the organic layer was washed with sodium carbonate, brine, dried and concentrated under reduced pressure. The crude mixture was purified by flash chromatography on silica (eluent 20 to 100% ethyl acetate in heptane) to yield 0.120 g (60%) of N-(2-(5-bromo-1H-indol-3-yl)ethyl)-5-(2,5-difluorobenzyl)isoxazole-3-carboxamide as a white solid.
