Versuchsvorschrift
In an analogous manner to that described in Example 36c), the reaction of (E)-4-[2-(4-fluoro-phenyl)-vinyl]-phenylamine with itaconic acid yields the (RS)-(E)-1-{4-[2-(4-fluoro-phenyl)-vinyl]-phenyl}-5-oxo-pyrrolidine-3-carboxylic acid which was directly engaged in the next step without further purification and characterisation.
