実験手順

To a mixture of sodium hydride (60%, 116 mg), 7-[(2-aminopyridin-3-yl)oxy]naphthalen-2-ol (477 mg) and dehydrated THF (10 mL) was added a mixture of 2,2,2-trifluoroethyl 4-methylbenzenesulfonate (370 mg) and dehydrated THF (5 mL) at room temperature. The reaction mixture was stirred at 70° C. over the weekend, DMSO (10.00 mL) was added and the mixture was stirred at 120° C. for 1 hr. The reaction mixture was added to a saturated aqueous ammonium chloride solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (82 mg) as a pale-yellow viscous product.
