Reaction Steps

The 4-acetylbenzenesulfonamide prepared above (247 mg, 0.879 mmol, 1.0 equiv) was dissolved in 10 mL THF followed by the addition on 3.52 mL of a 0.5M solution of CF3TMS in THF. After 5 min, 229 mg of tetrabutylammonium fluoride hydrate (0.879 mmol, 1.0 equiv) was added to the stirring solution. After stirring 21 h the reaction mixture was diluted with sat. NaHCO3, extracted (2×EtOAc), dried (MgSO4) and concentrated under reduced pressure. Purification by flash chromatography (SiO2, 2% MeOH/CH2Cl2) gave the product as a white solid. 1H NMR (DMSO, 400 MHz) δ 7.80 (s, 4H), 6.84 (s, 1H), 3.21 (t, J=5.8 Hz, 4H), 1.71 (s, 3H), 1.63 (m, 4H), 1.50 (m, 4H).
