実験手順
1-(5-(4-Bromo-3,5-dimethoxyphenyl)thiophen-2-yl)-2-methoxy-2-(4-(5-methyl-1,3,4-oxadiazol-2-yl)phenyl)ethanone was prepared from 2-(4-bromo-3,5-dimethoxyphenyl)thiophene and N,2-dimethoxy-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 (70% EtOAc-hexanes) gave the product as a yellow foam (0.031 g, 11% yield). MS: m/z 529.2 [M+H]+.
