실험 절차

A solution of 4-chloro-3-(4-phenoxyphenyl)pyridin-2-amine (124 mg) in THF (dry) (5 mL) was added to a suspension of NaH (60%, 84.0 mg) and 2-chloroethanesulfonyl chloride (0.131 mL) in THF (dry) (5 mL) at 0° C. The mixture was stirred at room temperature overnight. Water and hexane were added to give a white precipitate. The precipitate was collected by filtration and washed with water and EtOAc, and then crystallized from THF-IPE to give the title compound (60.0 mg) as a white solid.
