To a solution of N-benzylbenzenesulfonamide (61.8 mg, 0.25 mmol), KBr (14.9 mg, 0.125 mmol), and Na2SO4 (71.0 mg, 0.50 mmol) in MeCN (1.5 mL) is added t-BuOCl (33.9 µL, 0.30 mmol) at room temperature, and the mixture is stirred at room temperature for 1 h. Then, TEMPO (7.8 mg, 0.050 mmol) is added and stirred at room temperature for 30 min. To the solution is added Na2CO3 (26.5 mg, 0.25 mmol), and the mixture is stirred at room temperature for 20 h. Subsequently, TMSCN (93.8 mL, 0.75 mmol) and LiClO4 (2.7 mg, 0.025 mmol) are added to the reaction mixture, and further stirred at room temperature for 22 h. Saturated Na2SO3 aqueous solution (10 mL) is added to the mixture, and the product is extracted with AcOEt (15 mL×3). The organic phase is washed with brine and dried over Na2SO4. The organic phase is concentrated under reduced pressure, and the crude product is purified by column chromatography (hexane : AcOEt = 3 : 1) to give the desired product (67.4 mg, Y. 99%).
