Procedure
In an analogous manner to that described in Example 24b), starting from (RS)-1-(4-benzyloxy-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid (Example 1a) by treatment with thionylchloride there is obtained (RS)-1-(4-benzyloxy-phenyl)-5-oxo-pyrrolidine-3-carbonyl chloride as a yellowish solid which is directly used in the next step without further purification.
