Reaction Steps

A mixture of 3-(4-phenoxyphenyl)pyridin-2-amine (47 mg) in dehydrated THF (5 mL) was added to a mixture of sodium hydride (60%, 35.8 mg) and 2-chloroethanesulfonyl chloride (88 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 ethyl acetate to give the title compound (53.2 mg) as a white solid. The obtained solid was crystallized from THF and diisopropyl ether to give a white solid.
