실험 절차
1-(5-(4-Chloro-3,5-dimethoxyphenyl)furan-2-yl)-2-ethoxy-2-(4-(5-methyl-1,3,4-oxadiazol-2-yl)phenyl)ethanone was prepared from 2-(4-chloro-3,5-dimethoxyphenyl)furan and 2-ethoxy-N-methoxy-N-methyl-2-(4-(5-methyl-1,3,4-oxadiazol-2-yl)phenyl)acetamide according to the procedure used in Example 30. Purification by chromatography (60% EtOAc-hexanes) gave the product as a pale yellow solid (0.122 g, 25% yield). MS: m/z 483.1 [M+H]+.
