Triethylamine → 1-(4-[2-[4-(2,4-Dioxothiazolidin-5-ylmethyl)phenoxymethyl]-1-methyl-1H-benzimidazol-6-yloxy]-2,6-dimethylphenyl)-3-[4-(trifluoromethyl)phenyl]urea

Participants

Reaction Steps

A mixture of 5-[4-[6-(4-amino-3,5-dimethylphenoxy)-1-methyl-1H-benzimidazol-2-ylmethoxy]benzyl]thiazolidine-2,4-dione dihydrochloride (288 mg), α,α,α-trifluoro-p-tolyl isocyanate (112 mg), triethylamine (121 mg) and anhydrous tetrahydrofuran (10 ml) was stirred at room temperature for 40 hours. The reaction mixture was concentrated and diluted with water. The precipitate was isolated by filtration and washed with water and ethyl acetate to afford the title compound (257 mg, mp 206-208° C.).
