N-Boc 1H-indole-3-sulfonamide (1.47 g, 4.96 mmol) was dissolved in CH3CN (75 mL), and NaI (3.72 g, 24.80 mmol) added. The mixture was cooled to 0° C. under N2, and tri-methylsilyl chloride (TMS-Cl, 2.69 g, 24.80 mmol) added dropwise, the mixture stirred for 15 min at 0° C., then stirred at RT overnight. The mixture was poured into water, the resulting off-white precipitate filtered, washed with water and hexane, and air dried to provide 1H-indole-3-sulfonic acid amide (947 mg, 97% yield), which was used without further purification.
