Participants

Reaction Steps

4-(4-Amino-benzenesulfonyl)-piperazine-1-carboxylic acid benzyl ester (0.25 g, 0.67 mmol) was dissolved in THF (10 ml). To this was added diisopropylethylamine (0.33 ml, 1.9 mmol) in one portion followed by the drop wise addition of acryloyl chloride (0.06 ml, 0.74 mmol) and the mixture was stirred at room temperature under a nitrogen atmosphere for 3 hours. The THF was removed under vacuum and the resulting crude material was purified by column chromatography (elution: 20% heptane, 80% ethyl acetate) to give the title compound (57 mg, 20% yield) as a white powder.
