Participants

Reaction Steps

Bis(2-hydroxyethyl)amine (5 g) was dissolved in N,N-dimethylformamide (100 ml), added with benzyl bromide (6.52 ml) and potassium carbonate (8.657 g) and stirred at room temperature for 21 hours. The reaction mixture was added with water (200 ml) and extracted twice with dichloromethane (200 ml). The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: dichloromethane:methanol=20:1→10:1) to obtain 7.631 g of the title compound. Yield: 75%.
