Procedure

A solution of ethyl (E)-3-[2-n-butyl-1-{(2-chlorophenyl)methyl}-4-(t-butyldimethylsilyloxy)methyl-1H-imidazol-5-yl]-2-(2-thienyl)methyl-2-propenoate (0.287 mmol) in absolute ethanol (3 mL) is treated portionwise with one equivalent of 10% sodium hydroxide solution. After being stirred overnight at 25° C., the reaction is heated to 50° C. for 4 hours, then concentrated in vacuo. The residual product is taken up in water, acidified to pH 5-6 and extracted with methylene dichloride. The isolated, dried, concentrated product is triturated with methanol/ether to provide the title compound.
