Versuchsvorschrift

A mixture of 3-[4-(cyclohexyloxy)phenyl]pyrazin-2-amine (470 mg) in THF (dry) (25.00 mL) was added to a mixture of NaH (60%, 349 mg) and 2-chloroethanesulfonyl chloride (853 mg) in THF (dry) (25 mL) at room temperature. The mixture was stirred at room temperature overnight and 80° C. for 3 hr. Water was added and THF was removed in vacuo. A precipitate was collected by filtration and washed with water-Et2O to give the title compound (522 mg) as a yellow solid. The solid was crystallized from CH3CN-IPE to give a yellow solid.
