実験手順

To a solution of 5-(5-(8-(trifluoromethyl)quinolin-4-yloxy)pentyloxy)-2-(hydroxymethyl)-4H-pyran-4-one 14 (430 mg, 1.02 mmol) in CH2Cl2 (15 mL) was added at 0° C. triethylamine (173 μL, 1.21 mmol), methanesulfonyl chloride (95 μL, 1.21 mmol). The solution was stirred at RT for 1 h. Dichloromethane (50 mL) was added and the solution was washed with water (2×100 mL), dried over MgSO4, filtered and evaporated. The crude product was purified by column chromatography on silica using as eluent (CH2Cl2:MeOH)=95:05. (5-(5-(8-(Trifluoromethyl)quinolin-4-yloxy)pentyloxy-4-oxo-4H-pyran-2-yl)methyl methanesulfonate 19 was obtained (188 mg, 37% yield) as a pale yellow oil.
