Versuchsvorschrift

(E)-3-[2-n-Butyl-1-[(2-chlorophenyl)methyl]-4-hydroxymethyl-1H-imidazol-5-yl]-2-(2-thienyl)methyl-2-propenoic acid, prepared as in Example 19, is esterified with 4-methoxy-benzyl alcohol to give the p-methoxybenzyl propenoate. The 4-hydroxymethyl group in acetone is oxidized using an acidic aqueous solution containing chromic acid (Jones' reagent) and the ester is hydrolyzed using 10% sodium hydroxide to give the title compound.
