    摘要: The subject matter of the invention is the new 2-azido-3-benzyloxy-propionic acid benzyl ester which is a valuable intermediate product for the production of D,L-serine or derivatives of D,L-serine. The new compound is produced by reacting 2-chloroacrylonitrile with twice the molar amount of benzyl alcohol to form 3-benzyloxy-2-chloropropionic acid imino benzyl ester, saponifying this with acid to form 3-benzyloxy-2-chloropropionic acid benzyl ester, and finally exchanging the chlorine atom by means of an alkali metal azide in the presence of a phase transfer catalyst for an azido group.
