Versuchsvorschrift

To a solution of 3-(chlorosulfonyl)benzoic acid (5 g, 22.66 mmol) in THF (50.4 mL) at 0° C. was added allylamine (2.038 mL, 27.2 mmol) followed by NaOH (1N aqueous) (49.9 mL, 49.9 mmol). The mixture was allowed to warm to RT over 1 hour and stirred an additional 16 hours. The mixture was diluted with 1N HCl (250 mL), and the aqeuous layer was extracted with EtOAc (300 mL). The organic layer was dried over sodium sulfate and concentrated to dryness to afford 3-(N-allylsulfamoyl)benzoic acid as white solid (5.2 g, 95% yield). MS m/z=242.0 [M+H]. Calc'd for C10H11NO4S: 241.0.
