실험 절차

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 (22 mg, 0.051 mmol) in CH2Cl2 (3 mL) were added Et3N (0.015 ml, 0.11 mmol) and hexahydro-pyrrolo[1,2-a]pyrazin-6-one (commercially available) (9 mg, 0.064 mmol). Stirring was continued overnight, and the reaction mixture was concentrated under vacuo and directly purified by flash chromatography (SiO2, EtOAc) to yield 7 mg (25%) the title compound as light yellow oil. ES-MS m/e: 539.2 (M+H+).
