Procedure

This compound was prepared according to method A with 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.100 g; 0.424 mmol), 1-(2,6-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid (0.107 g; 0.445 mmol), HATU (0.166 g; 0.437 mmol) and N,N-diisopropylethylamine (0.186 mL; 1.06 mmol) in DMF (5 mL). The crude material was purified by flash chromatography on silica gel (eluent: 2 to 20% of ethyl acetate in dichloromethane) to give 0.033 g (20%) of N-(2-(5-chloro-1H-indol-3-yl)ethyl)-1-(2,6-difluorophenyl)-2-oxopyrrolidine-3-carboxamide as a white solid.
