Reaction Steps

The method used for the final coupling step of Example 12 was followed for the reaction of 5-(furan-2-yl)-2,3-dimethoxybenzonitrile and N,2-dimethoxy-N-methyl-2-(4-(5-methyl-1,3,4-oxadiazol-2-yl)phenyl)acetamide except that the reaction was performed at −40 to −25° C. then warmed to room temperature. Purification by chromatography (20-100% EtOAc-hexanes) provided 2,3-dimethoxy-5-(5-(2-methoxy-2-(4-(5-methyl-1,3,4-oxadiazol-2-yl)phenyl)acetyl)furan-2-yl)benzonitrile (0.040 g, 13% yield). MS: m/z 460.2 [M+H]+.
