Combine 2-iminopyrrolidine hydrochloride (6.98 g, 57.8 mmol) (Callahan, et al., J. Med. Chem. 45, 999-1001 (2002)), 2-bromoacetophenone (3.8 g, 19.3 mmol), and sodium carbonate (8.2 g, 77.2 mmol) in dry dimethylformamide (25 mL). Heat at 80° C. for 18 hours. Cool to room temperature, add water (60 mL), and extract with ethyl acetate (3×100 mL). Concentrate the combined organic layers under reduced pressure. Dilute the residue with diethyl ether (100 mL), wash with cold water (3×80 mL), and concentrate under reduced pressure to provide the desired compound as a white solid (3.2 g, 89%).
