実験手順

4-[(4-Methylphenyl)methyl]-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-5-trifluoromethyl-1H-pyrazole was prepared in a similar manner to that described in Example 26 using 1,2-dihydro-4-[(4-methylphenyl)methyl]-5-trifluoromethyl-3H-pyrazol-3-one instead of 1,2-dihydro-4-[(4-methylthiophenyl)methyl]-5-trifluoromethyl-3H-pyrazol-3-one. Then, the title compound was prepared in a similar manner to that described in Example 35 using 4-[(4-methylphenyl)methyl]-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-5-trifluoromethyl-1H-pyrazole instead of 4-[(4-isopropoxyphenyl)methyl]-5-methyl-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-1H-pyrazole.
