Participants

Reaction Steps

This compound was prepared according to method E with 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.100 g; 0.433 mmol), 1-(2-ethylphenyl)-2-oxopyrrolidine-3-carboxylic acid (0.101 g; 0.433 mmol), PyBOP (0.225 g; 0.433 mmol), N,N diisopropylethylamine (0.186 mL; 1.08 mmol) in DMF (3 mL). The crude mixture was purified flash chromatography on silica (eluent 20 to 100% ethyl acetate in heptane) to yield 0.094 g (53%) of N-(2-(5-chloro-1H-indol-3-yl)ethyl)-1-(2-ethylphenyl)-2-oxopyrrolidine-3-carboxamide as a white solid.
