실험 절차

A mixture of 5-[4-[6-(4-n-hexylaminophenoxy)-1-methyl-1H-benzimidazol-2-ylmethoxy]benzyl]thiazolidine-2,4-dione (0.39 g), phenyl isocyanate (95 mg) and anhydrous tetrahydrofuran (20 ml) was allowed to stand at room temperature for 2 days. The reaction mixture was concentrated and partitioned between ethyl acetate and water. The extract was dried over anhydrous sodium sulfate and then concentrated. The residue was chromatographed on a silica gel column using ethyl acetate:n-hexane=3:2 as the eluant and the product was reprecipitated from a mixture of n-hexane and diethyl ether to afford the title compound (0.30 g, Rf=0.56: thin layer chromatography on a silica gel plate using ethyl acetate:n-hexane=2:1 as the eluant).
