실험 절차

The mixture of 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.256 g; 1.09 mmol), (S)-2-(1-hydroxy-3-phenylpropan-2-ylamino)-2-oxoacetic acid (0.267 g; 1.19 mmol), HATU (0.413 g: 1.09 mmol) and N,N-diisopropylethylamine (0.474 mL; 2.71 mmol) in DMF (5 mL) was stirred at room temperature overnight and concentrated under reduced pressure. The residue was dissolved in dichloromethane and the organic layer was washed with water and was concentrated under reduced pressure. The crude material was purified by flash chromatography on silica gel (eluent 1 to 10% methanol in dichloromethane) to yield 0.251 g (58%) of (S)-N1-(2-(5-chloro-1H-indol-3-yl)ethyl)-N2-(1-hydroxy-3-phenylpropan-2-yl)oxalamide as a white solid.
