実験手順

This compound was prepared following Method A starting from 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.505 g; 2.14 mmol), the INTERMEDIATE 14: 5-(tert-butoxycarbonylamino)isoxazole-3-carboxylic acid (0.513 g; 2.25 mmol), HATU (0.896 g; 2.36 mmol) and N,N-diisopropylethylamine (0.935 mL; 5.35 mmol) in DMF (5 mL). Flash chromatography on silica gel eluting with 2 to 20% of ethyl acetate in dichloromethane afforded 0.819 g (94%) of tert-butyl 3-(2-(5-chloro-1H-indol-3-yl)ethylcarbamoyl)isoxazol-5-ylcarbamate as a white solid.
