Reaction Conditions:

with sodium methylate in methanol at 30; for 1 h;Solvent;Reagent/catalyst;

Steps:

4.2 2) Synthesis of ethyl vanillin-β-D-glucopyranoside:
In a reaction flask, sodium methoxide (0.54 g, 10.0 mmol) and methanol (10 mL) were sequentially added, followed by ethyl vanillin tetra-O-acetyl-β-D-glucopyranoside (4.96 g, 10.0 mmol). ), reacted at 30 ° C for 1 h. After completion of the reaction, the system was neutralized by adding a methanol solution of hydrogen chloride to pH = 6.5. The solvent was removed under reduced pressure and purified by chromatography (methylene chloride:methanol = 10:1) to afford 3.02 g of white powder, mp 189 to 190 ° C.It is ethyl vanillin-β-D-glucopyranoside.
