Reaction Steps

4-aminobenzenesulfonamide (1.00 g) and pyridine (1.41 mL) were added to 1,4-dioxane (30 mL). Acryloyl chloride (0.49 mL) was added dropwise and the solution was stirred for 3 hours at room temperature. 1M HCl was added, and the solution extracted with ethyl acetate. The extracts were dried using brine and anhydrous sodium sulfate and the solvent was removed to afford crude product of sufficient purity for subsequent use.
