実験手順

Allylamine (10 mL, 0.13 mol) was cooled to 0° C., and a solution of bromoacetic acid tert-butyl ester (1.0 mL, 6.7 mmol) in dichloromethane (10 mL) was slowly added. After stirring at 0° C. for 3 hours, the reaction mixture was concentrated under reduced pressure. The obtained residue was dissolved in diethyl ether, washed successively with saturated aqueous sodium hydrogen carbonate and saturated brine, and dried over anhydrous sodium sulfate. The obtained solution was concentrated under reduced pressure to give the title compound as a yellow liquid (1.15 g, 6.7 mmol, 99%).
