실험 절차

80 g (0.73 mol) of ethyl chloroformate are added dropwise to 86.2 g (0.72 mol) of 2-aminopropionaldehyde dimethyl acetal in 350 ml of toluene and 32 g (0.8 mol) of NaOH in 300 ml of water. The mixture is stirred at room temperature for a further 2 hours, the organic phase is separated off, the aqueous phase is extracted with toluene and the toluene solutions are dried over K CO2. The solution is concentrated and the residue is distilled.
