실험 절차
To a solution of 3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-4-{[4-(2-carboxy-2-methylpropoxy)phenyl]-methyl}-5-isopropyl-1H-pyrazole (0.13 g) in N,N-dimethylformamide (2 mL) were added L-alanine amide hydrochloride (46 mg), triethylamine (0.08 mL), 1-hydroxybenzotriazole (38 mg) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.11 g), and the mixture was stirred at room temperature overnight. The reaction mixture was poured into water, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with water, a saturated aqueous sodium hydrogen carbonate solution, water and brine successively, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: dichloro-methane/methanol=20/1-10/1) to give the title compound (0.14 g).
