実験手順
To a solution of 3-methoxy-4-[5-(5-methyl-3-phenyl-isoxazol-4-yl)-[1,3,4]oxadiazol-2-yl]-phenylamine (200 mg, 0.57 mmol) in tetrahydrofuran (5 mL) were added N,N-diisopropylamine (111 mg, 0.86 mmol), 4-dimethylaminopyridine (7.0 mg, 0.06 mmol) and thiophenesulfonyl chloride (126 mg, 0.69 mmol) and the reaction mixture was stirred at ambient temperature for 4 d. The resulting suspension was extracted with ethyl acetate (20 mL) and the combined organic layers were washed with aqueous sodium carbonate (saturated). Drying over sodium sulfate and purification by chromatography (SiO2, heptane:ethyl acetate:dichloromethane=50:30:20 to 20:60:20) afforded the title compound (95 mg, 33%) as an orange solid. MS: m/e=495.1 [M+H]+.
