실험 절차
4-Bromoaniline (0.86 g, 5.0 mmol) was dissolved in CH2Cl2 (15 mL), pyridine (0.5 mL) was added, and 3-chloropropanesulfonyl chloride (0.6 mL, 5.0 mmol) was added. The mixture was stirred for 4 hours, diluted with ethyl acetate, and then washed with water, 2N HCl, brine, dried over MgSO4, and concentrated. The crude product was purified via Isco chromatography (the Redisep® column, silica, gradient 5-60% ethyl acetate in hexane) to afford 1.2 g (77%) N-(4-bromophenyl)-3-chloropropane-1-sulfonamide.
