실험 절차

To a solution of 4-{3-methoxy-4-[5-(5-methyl-3-phenyl-isoxazol-4-yl)-[1,3,4]oxadiazol-2-yl]-phenyl}-thiomorpholine (660 mg, 1.52 mmol) in dichloromethane (7 mL), methanol (7 mL) and water (0.1 mL) was added oxone (1.87 g, 3.04 mmol) and stirred for 8 h at 60° C. The reaction mixture was cooled to ambient temperature and aqueous sodium bisulfite (38%, 5 mL) was added and stirred for 1 h. After the addition of aqueous sodium carbonate (saturated, 30 mL) the mixture was extracted with dichloromethane (30 mL) and washed with aqueous sodium carbonate (half-saturated, 30 mL). Drying over sodium sulfate and purification by chromatography (SiO2, heptane:ethyl acetate:dichloromethane:methanol=40:40:20:0 to 0:75:20:5) afforded the title compound (102 mg, 15%) as an off-white solid. MS: m/e=451.1 [M+H]+.
