Procedure

To a mixture of NaH (60%, 2.59 g) and 2-chloroethanesulfonyl chloride (6.33 g) in THF (dry) (50 mL) was added a solution of 5-chloro-3-(4-phenoxyphenyl)pyridin-2-amine (3.84 g) in THF (dry) (50 mL) at room temperature. The mixture was stirred at room temperature overnight. Water and NH silica gel were added and the mixture was concentrated in vacuo. The residue was purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) to give the title compound (3.07 g) as a pale yellow solid. The solid was is crystallized from DMSO(15 mL)-EtOH(90 mL) to give a white solid.
