Versuchsvorschrift

1-[2-(4-[2-[4-(2,4-Dioxothiazolidin-5-ylmethyl)phenoxymethyl]-1-methyl-1H-benzimidazol-6-yloxy]phenyl)ethyl]-3-(4-trifluoromethylphenyl)urea hydrochloride 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), α,α,α-trifluoro-p-tolyl isocyanate (97 mg), triethylamine (65 mg) and anhydrous N,N-dimethylformamide (5 ml). To a solution of the product in tetrahydrofuran (10 ml) was added 4N hydrogen chloride in 1,4-dioxane (10 ml) and the mixture was stirred at room temperature for 3 hours. To the reaction mixture was added diethyl ether (50 ml) and this mixture was further stirred for 30 minutes. The precipitate was isolated by filtration and washed with ethyl acetate to afford the title compound (0.3 g, mp 153-156° C.).
