A mixture of 3-bromopyridin-2-amine (3 g) in dehydrated THF (30 mL) was added to a mixture of 2-chloroethanesulfonyl chloride (7.07 g) and sodium hydride (60%, 3.47 g) in dehydrated THF (30 mL) at room temperature, and the reaction mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and THF was removed under reduced pressure. The resulting precipitate was collected by filtration, and washed with water and diethyl ether to give the title compound (3.41 g) as a white solid.
