실험 절차

To a stirred solution of 5-bromo-pentanoyl chloride (0.167 ml, 1.25 mmol) in THF (10 ml) at RT was added over 1 hour a solution of [(3RS,4SR)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-(3-fluoro-4-trifluoromethyl-benzyl)-methyl-amine (Intermediate VIII-1, 0.50 g, 1.19 mmol) and triethyl amine (0.18 ml, 1.30 mmol) in THF (5 mL). The reaction was stirred over night, quenched by addition of an aqueous solution of NaHCO3, and the product extracted with EtOAC. Purification by flash chromatography (SiO2, EtOAc/Hx 1:1) yielded 0.58 g (83%) of the title compound as a white solid. ES-MS m/e: 584.4 (M+H+).
