الإجراء التجريبي

0.26 ml (2.4 mmol) of 4-methylmorpholine and 230 mg (1.2 mmol) of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (DAPECI) are added to a solution of 261 mg (1.00 mmol) of (R)-2-(4-chlorophenyl-carbamoyl)pyrrolidinium chloride and 235 mg (1.00 mmol) of 4-(3-oxomorpholin-4-yl)phenylacetic acid in 2 ml of DMF, and the mixture is stirred at room temperature for 18 hours. The reaction mixture is introduced into water, and the precipitate formed is filtered off, giving N-(4-chlorophenyl)-(R)-1-{2-[4-(3-oxomorpholin-4-yl)phenyl]acetyl}pyrrolidine-2-carboxamide as a slightly brownish solid; ESI 442.
