Benzoyl chloride → N-[4-(4-Benzoyl-piperazine-1-sulfonyl)-phenyl]-acrylamide

Participants

Reaction Steps

Diisopropylethylamine (0.24 ml, 1.36 mmol) was added in one portion to a stirred solution of N-[4-(piperazine-1-sulfonyl)-phenyl]-acrylamide (0.1 g, 0.34 mmol) in THF (5 ml). The mixture was stirred at room temperature for 5 minutes before benzoyl chloride (0.05 ml, 0.44 mmol) was added drop wise and the resulting mixture was stirred at room temperature under a nitrogen atmosphere for 18 hours. The crude reaction mixture was concentrated under vacuum and the residue was purified by Prep HPLC to give the title compound (0.018 g, 13% yield) as a white powder.
