반응 단계
The mixture of 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.210 g; 0.890 mmol), (R)-2-(1-hydroxy-3-phenylpropan-2-ylamino)-2-oxoacetic acid (0.219 g; 0.979 mmol), HATU (0.339 g: 0.890 mmol) and N,N-diisopropylethylamine (0.389 mL; 2.23 mmol) in DMF (5 mL) was stirred at room temperature overnight and concentrated under reduced pressure. The residue was dissolved in dichloromethane, 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 0.226 g (63%) of (R)-N1-(2-(5-chloro-1H-indol-3-yl)ethyl)-N2-(1-hydroxy-3-phenylpropan-2-yl)oxalamide as a white solid.
