To a stirred solution of (3SR,4RS)-3-(3,4-dichloro-phenyl)-4-[(SR)-1-(5-trifluoromethyl-pyridin-2-yloxy)-ethyl]-pyrrolidine-1-carbonyl chloride (30 mg, 0.064 mmol) in CH2Cl2 (3 mL) were added Et3N (0.015 mL, 0.11 mmol) and 2-Oxa-5-aza-bicyclo[2.2.1]heptane (commercially available) (7 mg, 0.070 mmol). Stirring was continued overnight, and the reaction mixture was concentrated under vacuo and directly purified by flash chromatography (SiO2, EtOAc) to yield 27 mg the title compound as a white solid. ES-MS m/e: 530.1 (M+H+).
