1,2-Dichloroethane → N-{4-[4-(3-Pyridin-3-yl-propionyl)-piperazine-1-sulfonyl]-phenyl}-acrylamide

Participants

Reaction Steps

Triethylamine (0.28 ml, 2.04 mmol) was added in one portion to a stirred solution of N-[4-(piperazine-1-sulfonyl)-phenyl]-acrylamide (0.2 g, 0.68 mmol) and 3-pyridine propionic acid (0.1 g, 0.68 mmol) in THF (5 ml). The mixture was stirred at room temperature for 5 minutes before EDC (0.26 g, 1.36 mmol) was added in one portion and the resulting mixture and stirred at room temperature under a nitrogen atmosphere for 18 hours. The crude reaction mixture was concentrated under vacuum and the resulting residue dissolved in DCM (20 ml), washed with water (20 ml), dried (MgSO4), filtered and concentrated under vacuum. The crude product was purified by Prep HPLC to give the title compound (0.046 g, 15% yield) as a white powder.
