反应详情

Bromoacetic acid (4.30 g) and N-hydroxysuccinimide (4.03 g) were dissolved in DCM (25 ml). The mixture was stirred on a magnetic stirrer at room temperature. DCC was added (7.42 g) in one portion and the mixture was reacted overnight. The reaction mixture was filtered to remove dicyclohexylurea. The filter cake washed several times with DCM. The combined filtrates were washed three times with saturated aqueous sodium chloride solution (30 mL/each wash), dried over anhydrous magnesium sulfate, and filtered. The title compound was obtained as a white solid (5 g) after rotary evaporation in vacuo.
