실험 절차

A mixture of 3-{[4-(1-methylethyl)phenyl]ethynyl}pyridin-2-amine (150 mg) in dehydrated THF (5 mL) was added to a mixture of sodium hydride (60%, 127 mg) and 2-chloroethanesulfonyl chloride (310 mg) in dehydrated THF (5 mL) under ice-cooling. The reaction mixture was stirred at room temperature for 2 hr, and saturated aqueous sodium hydrogen carbonate solution and ethyl acetate were added. The resulting precipitate was collected by filtration, and washed with water and ethyl acetate to give the title compound (110 mg) as a white solid. The obtained solid was crystallized from acetonitrile and diisopropyl ether to give a white solid.
