Ethyl bromoacetate → HCID 86663849, compound

Participants

Reaction Steps

To a solution of ethyl N-(tert-butoxycarbonyl)-N-(2-hydroxyethyl)glycinate (1.2 g) in THF (17 mL) was added ethyl bromoacetate (0.8 ml) under ice-cooling, and the mixture was stirred for 5 min. To this solution was added sodium hydride (288 mg), and the mixture was stirred under ice-cooling for 5 min, and at room temperature for 60 min. The reaction mixture was ice-cooled again, ice water was added, and the mixture was extracted with ethyl acetate. The extract was washed successively with water and brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (788 mg).
