Hydrochloric Acid → HCID 9847831, compound

Participants

Reaction Steps

To a solution of 2-(4-ethylbenzyl)-5-hydroxymethylphenyl β-D-glucopyranoside (0.075 g) in 2,4,6-trimethypyridine (2 mL) was added ethyl chloroformate (0.037 mL, 2 mol equivalent), and the mixture was stirred at room temperature for 17 hours. To the reaction mixture was added 1 mol/L hydrochloric acid, and the mixture was extracted with ethyl acetate. The extract was washed with 1 mol/L hydrochloric acid and water, and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by preparative thin layer chromatography on silica gel (eluent: dichloromethane/-methanol=10/1) and recrystallized (recrystallization solvent: acetone/hexane=1/1) to give 2-(4-ethylbenzyl)-5-hydroxymethylphenyl 6-O-ethoxycarbonyl-β-D-glucopyranoside (0.020 g).
