Methyl 3-(3,4-dimethoxyphenyl)propanoate → 2-Phenyl-1-{(2-chlorophenyl)methyl}-1H-imidazol-5-yl-2-(3,4-dimethoxy-phenyl)methyl-2-propenoic Acid

Participants

Reaction Steps

By the procedure of Example 1(ii) Method B, using benzamidine methyl ether in place of valeramidine methyl ether, 2-phenyl-5-hydroxymethylimidazole is prepared and converted to 2-phenyl-1-(2-chlorophenyl)methyl-5-hydroxymethyl-1H-imidazole. The 5-hydroxymethyl group is oxidized using manganese dioxide by the procedure of Example 1 (iii). The resulting 2-phenyl-1-(2-chlorophenyl)methyl-1H-imidazol-5-carboxaldehyde is used in the procedure of Example 27 with methyl 3-(3,4-dimethoxyphenyl)propanoate to give the title compound.
