1-(Adamant-1-yl)-3-[2-(4-[2-[4-(2,4-dioxothiazolidin-5-ylmethyl)phenoxymethyl]-1-methyl-1H-benzimidazol-6-yloxy]phenyl)ethyl]urea was obtained by a similar procedure to that described in Example 31 using 5-[4-[6-[4-(2-aminoethyl)phenoxy]-1-methyl-1H-benzimidazol-2-ylmethoxy]benzyl]thiazolidine-2,4-dione dihydrochloride (0.3 g), 1-adamantyl isocyanate (94 mg), triethylamine (65 mg) and anhydrous N,N-dimethylformamide (15 ml). To a solution of the product in tetrahydrofuran (10 ml) was added 4N hydrogen chloride in dioxane (10 ml) and the mixture was stirred at room temperature for 3 hours. The precipitate was isolated by filtration and washed with tetrahydrofuran and n-hexane to afford the title compound (0.3 g, mp 174-176° C.).
