Procedure
In an analogous manner to that described in Example 28b), the alkylation of the (R)-1-(4-hydroxy-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid methyl ester [Example 28a)] with 2,6-difluorobenzylalcohol yields the (R)-1-[4-(2,6-difluoro-benzyloxy)-phenyl]-5-oxo-pyrrolidine-3-carboxylic acid methyl ester as a white solid. MS: m/e=362 (M+H)+.
