    摘要: The invention relates to a method for the production of β-aminopropionic acid derivatives by reaction of a primary or secondary amine with an acrylic acid derivative, wherein (i) a first primary or secondary amine is provided as amine of value and is reacted with the acrylic acid derivative, wherein a reaction mixture containing a first β-aminopropionic acid derivative is obtained as product of value and in addition unreacted acrylic acid derivative is obtained, (ii) the unreacted acrylic acid derivative contained in the reaction mixture is reacted virtually completely with a second secondary amine as trapping amine to give a second β-aminopropionic acid derivative, wherein a reaction mixture is obtained which contains the first β-aminopropionic acid derivative as product of value, the second β-aminopropionic acid derivative and unreacted secondary amine.
