Product 1

HCID 552206635-Oxo-pyrrolidine-3-carboxylic acid methylamide

Procedure

In an analogous manner to that described in Example 24f), by condensing (R)-1-(4-benzyloxy)-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid with methylamine using HBTU as the condensation agent there is obtained (R)-1-(4-benzyloxy)-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid methylamide as a white solid. MS: m/e=325 (M+H)+; [α]589=−27.55° (c=0.958, CH2Cl2).
