실험 절차
2-(4-(5-Cyclopropyl-1,3,4-oxadiazol-2-yl)phenyl)-N,2-dimethoxy-N-methylacetamide was reacted with 2-(4-bromo-3,5-dimethoxyphenyl)furan according to the procedure for the synthesis of Example 12. Purification by chromatography (EtOAc-hexanes) gave 1-(5-(4-bromo-3,5-dimethoxyphenyl)furan-2-yl)-2-(4-(5-cyclopropyl-1,3,4-oxadiazol-2-yl)phenyl)-2-methoxyethanone as a yellow foam (0.126 g, 31% yield). MS: m/z 539.2 [M+H]+.
