Procedure

A mixture of 3-[4-(trifluoromethoxy)phenyl]pyridin-2-amine (350 mg) in dehydrated THF (5 mL) was added to a mixture of sodium hydride (60%, 275 mg) and 2-chloroethanesulfonyl chloride (673 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 (333 mg) as a white solid. The obtained solid was crystallized from THF, acetonitrile and diisopropyl ether to give a white solid.
