Reaction Steps

A solution of 3-(4-phenoxyphenyl)pyrazin-2-amine (1.97 g) in THF (dry) (20 mL) was added to a suspension of NaH (60%, 1.50 g) and 2-chloroethanesulfonyl chloride (2.35 mL) in THF (dry) (20 ml) at 0° C. The mixture was stirred at room temperature overnight then at 80° C. for 4 hr. After cooling to room temperature, the mixture was added with water and EtOAc. The precipitate was collected by filtration, washed with water and EtOAc, and then recrystallized from EtOH-EtOAc to give the title compound (1.68 g) as a pale yellow solid.
