Reaction Steps

2-Chloroethanesulfonyl chloride (19.5 mL) was added dropwise to a mixture of NaH (60%, 12.5 g) in THF (100 mL) at 0° C. in an ice bath. After being stirred at 0° C. for 10 min, a solution of 3-[4-(4-methylphenoxy)phenyl]pyridin-2-amine (17.2 g) in THF (100 mL) was added dropwise to the mixture at 0° C. The ice-bath was removed and the mixture was stirred at room temperature under N2 for 14 hr. The mixture was quenched with EtOH at 0° C. and water was added dropwise to the mixture at 0° C. The mixture was stirred at room temperature for 1 h. The precipitate was collected by filtration, and washed with water and EtOAc to give the title compound (8.68 g) as colorless powder.
