Aniline (0.98 mL, 10.7 mmol) and Et3N (1.8 mL, 12.9 mmol) in toluene (25 mL) were treated with 2-chloro-1-ethanesulfonylchloride (1.1 mL, 10.5 mmol). The exothermic reaction was stirred for 14 hours at room temperature. After stirring, the solution was diluted with EtOAc and washed with HCl (˜10% aq. soln.). The organic layer concentrated and purified via flash column chromatography (4:1 hexane/EtOAc) to afford two lots of phenyl(vinylsulfonyl)amine.
