Reaction Steps
The procedure of Example 1, Method A is used. 2-n-Butyl-1-(2-chloro-6-fluorophenyl)-methyl-1H-imidazole-5-carboxaldehyde, trimethyl 3-(2-thienyl)-2-phosphonopropionate, sodium hydride and glyme are held at 60° C. for 1 hour to give, after chromatography over silica gel with 50% of hexane in ethyl acetate, methyl (E)-[2-n-butyl-1-{(2-chloro-6-fluorophenyl)methyl}-1H-imidazol-5-yl]-2-(2-thienyl)methyl-2-propenoate and corresponding cis or (Z)-isomer. The (E)-isomer is hydrolyzed to afford (E)-3-[2-n-butyl-1-{(2-chloro-6-fluorophenyl)methyl}-1H-imidazol-5-yl]-2-(2-thienyl)methyl-2-propenoic acid.
