A mixture of (R)-3-amino-1-(4-chlorobenzyl)pyrrolidine-dihydrochloride (4.54 g, 16.0 mmol), a 2M NaOH solution (80 mL), and ethyl acetate (80 mL) was stirred, and the organic layer was then separated. The aqueous layer was extracted with ethyl acetate (80 mL×2). The obtained organic layers were combined, dried over anhydrous sodium sulfate, filtered, and then concentrated to obtain the free (R)-3-amino-1-(4-chlorobenzyl)pyrrolidine (3.35 g, 99%).
