5-Adamantan-1-yl-2,3-dioxo-pentanoic acid ethyl ester monohydrate (Example 44) was reacted with 2-fluorobenzaldehyde according to the procedure of Example 20, step b to produce 5-(2-adamantan-1-yl-ethyl)-2-(2-fluoro-phenyl)-1H-imidazole-4-carboxylic acid ethyl ester. The ester was hydrolyzed according to the procedure of Example 20, step c and the resulting 5-(2-adamantan-1-yl-ethyl)-2-(2-fluoro-phenyl)-1H-imidazole-4-carboxylic acid was reacted with 3-amino-benzoic acid benzyl ester using essentially the same procedure as in Example 20, step d. Deprotection was carried out according to the procedure of Example 20, step e to afford the title compound as a colourless foam.
