Reaction Steps

To a stirred suspension of 4-(methylsulfonyl)aniline hydrochloride (2.0 g, 9.7 mmol) in EtOH (40 mL) was added KOtBu (1.3 g, 11.4 mmol). The reaction mixture was stirred for 15 minutes, then a slurry of silver sulfate (3.3 g, 10.6 mmol) and iodine (2.4 g, 9.6 mmol) in EtOH (100 mL) was added. The reaction mixture was stirred at 50° C. for 3 h, then cooled to r.t., filtered through Celite®, and the filtrate concentrated in vacuo. Recrystallisation from EtOH gave the title compound (1.9 g, 66%) as an off-white solid. LCMS (ES+) 319.8 (M+Na)+, RT 2.77 minutes (Method 5).
