実験手順

To a solution of 1-acetyl-4-[(4-ethylthiophenyl)-methyl]-3-(β-D-glucopyranosyloxy)-5-methylpyrazole (0.03 g) in 2,4,6-trimethylpyridine (0.5 mL) was added ethyl chloro-formate (0.012 mL), and the mixture was stirred at room temperature overnight. To the reaction mixture was added 10% aqueous citric acid solution (5 mL), and the resulting mixture was stirred at room temperature overnight. The resulting precipitatse were collected by filtration and washed with 10% aqueous citric acid solution and water to give 1-acetyl-3-(6-O-ethoxycarbonyl-β-D-glucopyranosyloxy)-4-[(4-ethylthiophenyl)methyl]-5-methylpyrazole (0.020 g).
