実験手順

A mixture of 3-biphenyl-4-ylpyridin-2-amine (700 mg) in dehydrated THF (30 mL) was added to a mixture of sodium hydride (60%, 568 mg) and 2-chloroethanesulfonyl chloride (1390 mg) in dehydrated THF (30 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 (652 mg) as a white solid.
