To a stirred solution of (3SR,4RS)-3-[(RS)-1-(5-chloro-pyridin-2-yloxy)-ethyl]-4-(3,4-dichloro-phenyl)-pyrrolidine-1-carbonyl chloride (80 mg, 0.18 mmol) in CH2Cl2 (2 mL) were added Et3N (0.03 mL, 0.15 mmol) and dimethyl-(2-piperazin-1-yl-ethyl)-amine (0.035 mL) (commercially available). Stirring was continued overnight, and the reaction mixture was concentrated under vacuo and directly purified by flash chromatography (SiO2, CH2Cl2/MeOH/NH3, 9/4/1) to yield 36 mg (35%) the title compound as light yellow oil. ES-MS m/e: 553.8 (M+H+).
