In an analogous manner to that described in Example 24f, by condensing (S)-1-(4-benzyloxy)-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid with methylamine using HBTU as the condensation agent there is obtained (S)-1-(4-benzyloxy)-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid methylamide as a white solid. MS: m/e=325 (M+H)+; [α]589=+32.02° (c=1.037, CH2Cl2).
