실험 절차
To a suspension of NaH (60%, 215 mg) in THF (dry) (20 mL) was added 2-chloroethanesulfonyl chloride (0.339 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-(4-(3-ethylphenoxy)phenyl)pyridin-2-amine (312 mg) in THF (dry) (30 ml) was added at 0° C. and the mixture was stirred at room temperature for 1 hr. The mixture was quenched with water at 0° C. Water and EtOAc/THF were added and the extracted organic layer was washed with brine. Silica-gel was added to the organic layer and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) and washed with IPE/EtOAc to give the title compound (295 mg) as a white solid. A part of this was recrystallized from THF/IPE.
