実験手順

To a suspension of NaH (60%, 241 mg) in THF (dry) (25 mL) was added 2-chloroethanesulfonyl chloride (0.380 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-(4-(4-fluoro-2-methylphenoxy)phenyl)pyridin-2-amine (354 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, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was washed with IPE/EtOAc, dried in vacuo to give the title compound (375 mg) as a slightly yellow solid. A part of this was recrystallized from MeCN/IPE.
