Reaction Steps

To 2,6-difluoro-3-(propane-1-sulfonylamino)-benzoic acid (6, 1.50 g, 5.4 mmol), 7.0 mL of toluene and thionyl chloride (15.0 mL, 0.21 mmol) were added. The reaction was heated to reflux for 3 hours, then concentrated to give crude compound (7) that was used in the next step without further purification.
