Reaction Steps

To a suspension of NaH (60%, 284 mg) in THF (dry) (25 mL) was added 2-chloroethanesulfonyl chloride (0.448 ml) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-(4-(2-methyl-4-(trifluoromethyl)phenoxy)phenyl)pyridin-2-amine (489 mg) in THF (dry) (40 mL) was added at 0° C. and the mixture was stirred at room temperature overnight. The mixture was quenched with water at 0° C. Water, EtOAc and 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 to give the title compound (390 mg) as a white solid. A part of this was recrystallized from MeCN/IPE.
