1,2-dihydro-5-methyl-4-[(4-methylphenyl)methyl]-3H-pyrazol-3-one → 3-(beta-D-Glucopyranosyloxy)-5-methyl-4-[(4-methylphenyl)methyl]-1H-pyrazole

Participants

Reaction Steps

5-Methyl-4-[(4-methylphenyl)methyl]-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-1H-pyrazole was prepared in a similar manner to that described in Reference Example 17 using 1,2-dihydro-5-methyl-4-[(4-methylphenyl)methyl]-3H-pyrazol-3-one instead of 1,2-dihydro-4-[(4-isopropoxyphenyl)methyl]-5-methyl-3H-pyrazol-3-one. Then, the title compound was prepared in a similar manner to that described in Reference Example 37 using 5-methyl-4-[(4-methylphenyl)methyl]-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-1H-pyrazole instead of 4-[(4-isopropoxyphenyl)methyl]-5-methyl-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-1H-pyrazole.
