반응 단계
A mixture of 4-[(4-bromophenyl)methyl]-5-methyl-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-1H-pyrazole (0.099 g), 4-fluorophenylboronic acid (0.046 g), cesium fluoride (0.050 g) and tetrakis(triphenylphosphine)palladium(0) (0.0038 g) in 1,2-dimethoxyethane (1.3 mL), ethanol (0.3 mL) and water (0.3 mL) was stirred at 85° C. for 18 hours. The reaction mixture was purified by column chromatography on silica gel (eluent: hexane/ethylacetate=1/1-1/2-1/5) to give 4-{[4-(4-fluorophenyl)phenyl]methyl}-5-methyl-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-1H-pyrazole (0.061 g).
