実験手順
To a solution of 5-fluoro-3-isobutyl-benzo[b]thiophene 0.55 g) in chloroform (10 ml) was added chlorosulfonic acid (1.54 g), and the resulting mixture was stirred at rt for 3 h, quenched with ice/water, and extracted with methylene chloride. The organic phases were washed with water and aqueous sodium bicarbonate solution, dried and concentrated. The residue was chromatographed on silica gel using heptane/ethyl acetate as eluent to obtain the title compound (0.49 g) as a colorless oil. MS (EI): 306.8 (M)
