실험 절차

A mixture of 3-[4-(1-methylethoxy)phenyl]pyridin-2-amine (350 mg) in dehydrated THF (5 mL) was added to a mixture of sodium hydride (60%, 307 mg) and 2-chloroethanesulfonyl chloride (750 mg) in dehydrated THF (5 mL) under ice-cooling. The reaction mixture was stirred at room temperature overnight, and water and hexane were added. The resulting precipitate was collected by filtration, and washed with water and diisopropyl ether to give the title compound (360 mg) as a white solid. The obtained solid was crystallized from THF, acetonitrile and diisopropyl ether to give a white solid.
