Reaction Steps
20.00 g (0.13 mol) of ethyl (2S)-2-aminopropanoate hydrochloride were added to a solution of 10.95 g (0.13 mol) of diketene in 500 ml toluene at 0° C. Then, 21.90 g (0.26 mol) NaHCO3 was added and the reaction mixture was stirred overnight at room temperature. Since no more starting material was detected by thin-layer chromatography, the reaction mixture was filtered, evaporated and the residue purified by column chromatography. This gave 19.36 g (0.096 mol, 74% yield) of a colorless oil.
