Procedure

In an analogous manner to that described in Example 2c), the alkylation of the (S)-[1-(4-hydroxy-phenyl)-2-oxo-pyrrolidin-3-yl]-carbamic acid tert-butyl ester [Example 16 a)] with 3,4-difluorobenzylbromide in presence of potassium carbonate yields the title compound as a white solid; MS: m/e=419 (M+H)+.
