Hydrochloric Acid → N-(2-Fluoro-4-iodophenyl)methanesulfonamide

참여 물질

반응 단계

2-fluoro-4-iodophenylamine (1.50 g) was dissolved in dichloromethane (40 ml) and to the solution were added pyridine (1.02 ml) and methanesulfonylchloride (700 μl). The mixture was stirred at room temperature for 1 hour and 1.5 N aqueous hydrochloric acid was added thereto to quench the reaction. The resulting mixture was extracted with dichloromethane, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The obtained residue was column-chromatographed (ethyl acetate/hexane=1/1) to yield the compound 3-2 (1.89 g, 95%).
