실험 절차

N-Benzoylglycine (9.3 mg, 0.055 mmol), 3-ethyl-1-[3-(dimethylamino)propyl]carbodiimide hydrochloride (EDCI) (1.05 mg) and 1-hydroxybenzotriazole hydrate (HOBt) (7.4 mg) were added to a chloroform (2.5 mL) solution of 3-amino-1-(4-chlorobenzyl)pyrrolidine dihydrochloride (14.2 mg, 0.050 mmol) and triethylamine (15.2 mg). The resulting reaction mixture was stirred at 25° C. for 16 hours and then washed with a 2 M aqueous solution of NaOH (2 mL×2) and brine. After filtration through a PTFE membrane filter, the solvent was removed under reduced pressure to provide 3-(N-benzoylglycyl)amino-1-(4-chlorobenzyl)pyrrolidine (Compd. No. 1) as an off-white oil (17.7 mg, 95%). The purity was determined by RPLC/MS (95%). ESI/MS m/e 372.0 (M++H, C20H22ClN3O2).
