Reaction Steps
A mixture of 3-(aminomethyl)-1-(4-chlorobenzyl)pyrrolidine (860 mg, 3.8 mmol), Et3N (5.7 mmol), N-tert-butoxycarbonylglycine (704 mg), EDCI (594 mg), HOBt (673 mg), and dichloromethane (20 mL) was stirred at room temperature for 15 h. Dichloromethane (50 mL) was added and the solution was washed with 2 N NaOH solution (50 mL×2), dried over anhydrous sodium sulfate, filtered, and concentrated to afford 3-[{N-(tert-butoxycarbonyl)glycyl}aminomethyl]-1(4chlorobenzyl)pyrrolidine (1.31 g, 90%).
