실험 절차

A solution of 5-(2,5-difluorobenzyl)isoxazole-3-carboxylic acid (0.080 g, 0.334 mmol), 2-(5-chloro-2-methyl-1H-indol-3-yl)ethanamine hydrochloride (0.090 g; 0.368 mmol), HATU (0.127 g; 0.334 mmol) and N,N-diisopropylethylamine (0.144 mL; 0.836 mmol) in DMF (5 mL), was stirred at room temperature for 18 hours. The reaction mixture was partitioned between ethyl acetate and a solution of sodium hydrogen sulfate. The organic layer was washed with sodium carbonate, brine, dried and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (eluent 20 to 100% ethyl acetate in heptane) to afford 0.090 g (62%) of the title compound as a pink solid.
