Triethylamine (0.021 mL, 0.15 mmol), 4-(dimethylamino)benzoic acid (10 mg, 0.061 mmol), EDCI (10.2 mg, 0.053 mmol) and HOBt (7.5 mg, 0.055 mmol) were added to a chloroform (2 mL) solution of (R)-1-(4-chlorobenzyl)-3-(glycylamino)pyrrolidine (13.8 mg, 0.052 mmol). The resulting reaction mixture was stirred at room temperature for 15 hours. The solution was washed with a 2 M aqueous solution of NaOH (2 mL×2) and brine (2 mL), filtered through a PTFE membrane by using dichloromethane (3 mL), dried and concentrated to thereby afford (R)-1-(4-chlorobenzyl)-3-[[N-(4-dimethylaminobenzoyl)glycyl]amino]pyrrolidine (Compd. No. 952) (24.9 mg). The purity was determined by RPLC/MS (91%). ESI/MS m/e 415.0 (M++H, C22H27ClN4O2).
