실험 절차

A mixture of 5-[4-[6-(8-aminonaphthalen-2-yloxy)-1-methyl-1H-benzimidazol-2-ylmethoxy]benzyl]thiazolidine-2,4-dione (0.4 g), p-toluenesulfonyl chloride (0.30 g), triethylamine (0.16 g) and anhydrous tetrahydrofuran (8 ml) was stirred at 50° C. for 5 hours and then at 70° C. for 2 hours. The reaction mixture was concentrated. To the residue was added water and the precipitate was washed with water and tetrahydrofuran to afford the title compound (0.14 g, mp 137-144° C.).
