実験手順

To a stirred solution of bromo-acetyl chloride (0.146 ml, 1.75 mmol) in THF (15 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, 0.70 g, 1.66 mmol) and triethyl amine (0.25 ml, 1.83 mmol) in THF (10 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 0.63 g (70%) of the title compound as a white solid. ES-MS m/e: 542.6 (M+H+).
