Reaction Steps
69.26 g (404 mmol) of α-bromopropionic acid chloride is added in drops at 0° C. to 30 g (336.7 mmol) of alanine and 102.2 g (1010.2 mmol) of triethylamine in 600 ml of methylene chloride. In this case, the temperature remains between 0° C.-5° C. 1000 ml of 5% aqueous hydrochloric acid is added, and the organic phase is separated. The organic phase is extracted once more with 400 ml of 5% aqueous hydrochloric acid, dried on magnesium sulfate and evaporated to dryness in a vacuum. The residue is recrystallized from acetone/diisopropyl ether.
