実験手順

A mixture of 5-chloro-3-{4-[(5-chloropyridin-2-yl)oxy]phenyl}pyridin-2-amine (440 mg) in THF (dry) (10 mL) was added to a mixture of NaH (60%, 265 mg) and 2-chloroethanesulfonyl chloride (648 mg) in THF (dry) (10 mL) at room temperature. The mixture was stirred at room temperature overnight and 80° C. for 3 hr. Water was added and the mixture was concentrated in vacuo. The residue was washed with water and Et2O to give an off-white solid. The solid was purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) to give the title compound (520 mg) as an off-white solid. The solid was crystallized from CH3CN—IPE to give a white solid.
