Procedure

0.21 g (0.98 mmol) of pyridinium chlorochromate (PCC) is added to the solution of 0.3 g (0.65 mmol) of 1-N-[(4-chlorophenyl)]-2-N-{[4-(3-oxomorpholin-4-yl)phenyl]}-(1R,4R)-4-hydroxypyrrolidine-1,2-dicarboxamide (Example 7) in 15 ml of methylene chloride, and the reaction mixture is stirred at room temperature for 48 hours. The precipitate is subsequently filtered off, and the filtrate is washed three times with 20 ml of water each time and dried over sodium sulfate. After the solvent has been stripped off, the residue is purified by preparative HPLC, giving 140 mg (47%) of 1-N-[(4-chlorophenyl)]-2-N-{[4-(3-oxomorpholin-4-yl)phenyl]}-(R)-4-oxo-pyrrolidine-1,2-dicarboxamide as a white powder, ESI 457, m.p. 154°.
