Versuchsvorschrift
2-Ethoxy-2-(4-(5-methyl-1,3,4-oxadiazol-2-yl)phenyl)-1-(5-(3,4,5-trimethoxyphenyl)furan-2-yl)ethanone was prepared from 2-(3,4,5-trimethoxyphenyl)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 (0.060 g, 15% yield). MS: m/z 479.4 [M+H]+.
