To a solution of 1-(N-(3-butenyl)pentafluorophenylsulfonamido)-4-methoxybenzene (410 mg, 1.01 mmol) in THF (6.5 mL) at −78° C. was added BH3.THF (1.00 mL of a 1 M solution in THF, 1.00 mmol). After stirring at −78° C. for 1 h and at 0° C. for 1 h, the reaction mixture was treated with H2O (20 mL) and sodium perborate (513 mg, 5.14 mmol). After stirring at rt for 2 h, the mixture was poured onto H2O (20 mL) and extracted with CH2Cl2 (3×15 mL). The combined organic extracts were washed with sat. NaCl (20 mL) and dried (MgSO4). Concentration followed by chromatography (2:1/hexanes:EtOAc) afforded 270 mg (64%) of product as a white solid, mp 88-90° C. 1H NMR (CDCl3): d 7.08(m, 2H), 6.85(m, 2H), 3.80(s, 3H), 3.77(m, 2H), 3.64(t, J=6.0; 2H), 1.63-1.55(m, 5H), 1.50(bs, 1H). Anal. Calcd. for C17H16F5NO4S: C, 48.00; H, 3.79; N, 3.29; S, 7.54. Found: C, 48.08; H, 3.76; N, 3.34; S, 7.46.
