Reaction Steps

A mixture of 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.100 g; 0.434 mmol), PyBOP (0.340 g; 0.651 mmol), N,N-diisoprpylethylamine (0.224 mL; 1.30 mmol) and 1-(4-cyanophenyl)-2-oxopyrrolidine-3-carboxylic acid (0.100 g; 0.434 mmol) was stirred in DMF (3 mL) overnight. The reaction mixture was partitioned between ethyl acetate and sodium hydrogen sulfate, the organic layer was washed with sodium carbonate, brine, dried and concentrated under reduced pressure. The crude mixture was purified preparative HPLC (method 1) to yield 0.006 g (3%) of the title compound as a white solid.
