Reaction Steps

The title compound was prepared using 2-n-butyl-1-[(4carbomethoxyphenyl)methyl]imidazole-5-aldehyde (prepared by the method described for the preparation of 2-n-butyl-1-[(4-carboethoxy-2-chlorophenyl)methyl]imidazole-5-aldehyde in Example 42) and t-butyl 3-(2-thienyl)-propanoate by the procedure of Example 1 (iv, Method B), except, instead of basic hydrolysis, trifluoroacetic acid hydrolysis of the t-butyl ester was employed; mp 217°-220° C.
