Reaction Steps

A mixture of 5-chloro-3-[4-(cyclohexyloxy)phenyl]pyridin-2-amine (210 mg) in THF (dry) (10 mL) was added to a mixture of NaH (60%, 139 mg) and 2-chloroethanesulfonyl chloride (339 mg) in THF (dry) (10.0 mL) at room temperature. The mixture was stirred at room temperature overnight. Water was added and the mixture was concentrated in vacuo. The residue was washed with water and IPE to give the title compound (232 mg) as a pale yellow solid. The solid was crystallized from EtOAc-hexane to give a pale yellow solid.
