Embodiment 1
[0303] 4-({4-[3-(carbamoylmethylcarbamoyl)propyl]phenyl}methyl)-3-(β-D-glucopyranose Oxy)-5-isopropyl-1H-pyrazole
[0304] To 3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-4-({4-[(1E)-3-carboxyprop-1-ene base]phenyl}methyl)-5-isopropyl-1H-pyrazole (0.34g) in N,N-dimethylformamide (1mL) solution, add glycinamide hydrochloride (0.12g ), 1-hydroxybenzotriazole (0.09g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.15g) and triethylamine (0.27g) , and the mixture was stirred overnight at room temperature. Insoluble material was removed by filtration. To the filtrate, 5 mol / L aqueous sodium hydroxide solution (0.5 mL) was added, and the mixture was stirred at room temperature for 1 hr. The insoluble matter was removed by filtration, and then the filtrate was purified by preparative reverse column chromatography (Shiseido CAPCELL PAK UG120 ODS, 5 μm, 120 Å, 20×50 mm, flow rate 30 mL / min linear gradient, water / acetonitrile=90 / 10-10 / 90), giving 4-({4-[(1E)...
