Procedure

To a suspension of NaH (60%, 220 mg) in THF (dry) (20 mL) was added 2-chloroethanesulfonyl chloride (0.347 mL) at 0° C. and the mixture was stirred for 10 min at the same temperature. A solution of 3-(4-(4-chloro-3-methoxyphenoxy)phenyl)pyridin-2-amine (359 mg) in THF (dry) (10 mL) was added at 0° C. and the mixture was stirred at room temperature under a dry atmosphere with anhydrous calcium chloride tube overnight. The mixture was quenched with water/THF then water at 0° C. and extracted with EtOAc/THF. Silica-gel was added to the organic phase and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (silica gel, eluted with MeOH in EtOAc) and concentrated in vacuo and washed with IPE to give the title compound (306 mg) as a white solid. A part of product was recrystallized from MeCN/IPE.
