Yield:3767-28-0 51%
Reaction Conditions:
with sodium methylate in methanol;
Steps:
2.5 5. Preparation of p-nitrophenyl-α-D-glucopyranoside substrate of formula (VIII-2)
11.7 g of the compound of the formula (VI-2) was obtained above in a 250 mL round bottom flask.Add 90 mL of anhydrous methanol,Stir at room temperature and add 5.4 g of sodium methoxide.TLC (thin layer chromatography) detection,At the end of the reaction, the reaction solution was decolorized with 1 g of activated carbon.The insoluble material was removed by filtration, and concentrated to dryness under reduced pressure. The crude product was separated by silica gel column chromatography, and the solvent was methanol: dichloromethane (volume ratio) = 1:6.3.8 g of p-nitrophenyl-α-D-glucopyranoside substrate represented by white formula (VIII-2) was obtained.The yield was 51%.
