Procedure

2-Chloroethanesulfonyl chloride (0.410 mL) was added to a mixture of NaH (60%, 390 mg) in THF (dry) (8 mL) at 0° C. under nitrogen flow. The mixture was stirred at 0° C. for 5 min. The mixture of (E)-3-(4-styrylphenyl)pyridin-2-amine (531 mg) in THF (dry) (20 mL) was added dropwise and the mixture was stirred at room temperature under atmosphere overnight. The mixture was quenched with water at 0° C., and water, EtOAc and THF were added. The insoluble material was collected by filtration and crystallized from DMSO-EtOH to give the title compound (340 mg) as slightly pale yellow crystals.
