実験手順
A mixture of 5-[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yl]-1H-tetrazole (1.55 g), ethyl 2-iodomethylbenzoate (1.67 g) and potassium carbonate (1.80 g) in 2-butanone (15 ml) was stirred under reflux for 5 hours. After being cooled, the resulting mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to column chromatography on silica gel and eluted with a mixture of toluene and ethyl acetate. The fractions containing object compound were combined and concentrated under reduced pressure to give 5-[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yl]-2-[2-(ethoxycarbonyl)phenylmethyl]-2H-tetrazole (2.05 g) and 5-[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yl]-1-[2-(ethoxycarbonyl)phenylmethyl]-1H-tetrazole (0.24 g).
