실험 절차

To a solution of (7-hydroxy-2-benzofuranyl)(5-methyl-3-phenyl-4-isoxazolyl)methanone (example 4) (100 mg, 0.31 mmol) in DMF (5 mL) was added N-(chloroacetyl)isopropylamine (47 mg, 0.34 mmol) and potassium carbonate (173 mg, 1.25 mmol) and the reaction mixture was stirred at room temperature for 4 h. The mixture was then poured onto ice-water, and extracted with ethyl acetate. The combined organic layers were then washed with water and brine, dried over Na2SO4 and evaporated. Purification by chromatography (SiO2, heptane:ethyl acetate:=100:0 to 1:1) afforded the title compound (37 mg, 28%) as a white solid. MS m/e: 419.3 [M+H]+.
