実験手順

2-{2-{[2-(4-tert-Butylthiazol-2-yl)benzofuran-5-yloxy]methyl}phenoxy}pentanenitrile (430 mg) was dissolved in dimethylformamide (5 ml), and sodium azide (364 mg) and ammonium chloride (0.3 g) were added. The mixture was stirred at 120° C. for three hours. The reaction mixture was cooled and poured into water and extracted with ethyl acetate. The aqueous layer was extracted with ethyl acetate again and the combined organic layer was washed with brine and dried over magnesium sulfate. After concentration, the crude product was purified on a silica gel column (15 g) eluting with a mixed solvent of methylene chloride and methanol (2% vol.) to give 2-(4-tert-butylthiazol-2-yl)-5-{2-[1-(1H-tetrazol-5-yl)butoxy]phenylmethoxy}benzofuran (400 mg).
