Procedure

To a suspension of NaH (60%, 29.2 mg) in THF (dry) (2 mL) was added 2-chloroethanesulfonyl chloride (0.046 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-(4-phenylcyclohexyl)pyridin-2-amine (36.8 mg) in THF (dry) (2 mL) was added at 0° C. and the mixture was stirred at room temperature under nitrogen overnight. The mixture was quenched with water at 0° C. carefully and extracted with EtOAc. The organic layer was separated, washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with EtOAc in hexane) and crystallized from EtOAc-hexane to give the title compound (15.7 mg) as an off-white crystals.
