実験手順

5-Chloro-3-(4-(4-(trifluoromethyl)pyridin-2-yloxy)phenyl)pyridin-2-amine (470 mg) was added to a mixture of NaH (60%, 257 mg) and 2-chloroethanesulfonyl chloride (628 mg) in THF (dry) (10 mL) at room temperature. The mixture was stirred at room temperature overnight and 80° C. for 3 hr. Water was added and the mixture was concentrated in vacuo. The residue was washed with IPE to give the title compound (502 mg) as a yellow solid. The solid was crystallized from CH3CN-IPE to give a pale yellow solid (1st crop impure, 2nd crop (254 mg)). The 1st crop was purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) to give the title compound (263 mg) as a white solid.
