실험 절차

A mixture of 5-[4-[6-(4-aminophenoxy)-1-methyl-1H-benzimidazol-2-ylmethoxy]benzyl]thiazolidine-2,4-dione dihydrochloride (400 mg), 1-naphthyl isothiocyanate (148 mg), triethylamine (153 mg) and anhydrous N,N-dimethylformamide (8 ml) was stirred at room temperature for 1 hour and then allowed to stand overnight. The reaction mixture was concentrated and partitioned between ethyl acetate and water. The extract was washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate and then concentrated. The residue was chromatographed on a silica gel column using ethyl acetate:n-hexane=3:2→2:1→4:1→1:0 as the eluant to afford the title compound (301 mg, mp 185.8-188.1° C.).
