To a mixture of sulfonamide 1 (1.43 g, 5.00 ramol, NaHCO3 (1.68. g, water (6 mL, and 1 M aq CuSO4 (0.20 mL) in a 25 mL Erlenmeyer flask was added a solution of freshly prepared TfN3 (10 mL, 0.75 M in toluene, 7.5 mmol, followed by 40 mL of t-BuOH. The flask was loosely capped, and the solution was stirred vigorously behind a blast shield for 18 h at room temperature. The reaction mixture was transferred to a larger round-bottom flask, rinsing with water and toluene. With xylenes in the collection flask, the volatiles were removed by a rotary evaporator, causing precipitation. Filtration afforded 2 as a yellow powder (1.45 g, 93% yield, mp 78.5-79.5 °C, Rf, 0.46 (silica gel, hexanes:EtOAc 8:2, vmax(KBr disc)/cm-1 2138 (N3, 1589, 1503, 1362 (SO2, 1185, 1161 (SO2, 1097, 1028; 1H NMR (500 MHz, DMSO-d6) δ 8.15 d, J
