Reaction Steps
6-Chloropyridin-2-amine (0.3 g, 2 mmol) was dissolved in DCM (20 mL) and then pyridine (0.57 mL, 7.0 mmol) was added to the mixture with stirring. Then, benzenesulfonyl chloride (0.36 mL, 2.8 mmol) was added into the mixture. The mixture was allowed to stir under inert atmosphere for 2 hours. The mixture was diluted with DCM and saturated NaHCO3, and then the aqueous layer was extracted with DCM three times. The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. The crude material was purified by silica gel chromatography (10-100% EtOAc/hexanes) to provide N-(6-chloropyridin-2-yl)benzenesulfonamide (0.5 g, 80% yield) as a colorless oil. MS (ESI pos. ion) m/z: 254 (MH+). Calculated exact mass for C11H8ClNO2S: 253.
