실험 절차

To a solution of [3-(4-fluoro-phenyl)-5-methyl-isoxazol-4-yl]-methanol (1.0 g, 4.8 mmol) in THF (70 mL) was added 3-oxo-2,3-dihydro-isoxazole-5-carboxylic acid methyl ester (0.69 g, 4.8 mmol) and triphenylphosphine (1.65 g, 6.3 mmol) at ambient temperature under an argon atmosphere. Then diethyl azodicarboxylate (2.7 mL, 6.3 mmol) was added at 4° C. and the reaction mixture was stirred for 3 h at room temperature. Concentration and purification by chromatography (SiO2, heptane:ethyl acetate=100:0 to 7:3) afforded the title compound (958 mg, 60%) as a white solid. MS: m/e=333.2 [M+H]+.
