Procedure

tert-Butyl (3S)-pyrrolidin-3-ylcarbamate (0.65 g, 3.5 mmol), 1-[3-(trifluoromethyl)phenyl]piperidine-4-carboxylic acid (0.80 g, 2.9 mmol), triethylamine (0.82 mL, 5.8 mmol) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (1.4 g, 3.2 mmol) were mixed in dry methylene chloride (10 mL). After being stirred overnight, the reaction mixture was diluted with EtOAc and washed with saturated NaHCO3. The aqueous layer was extracted with EtOAc three times. The combined organic layers were dried (MgSO4), concentrated and flash chromatographed (20% EtOAc/hexanes to 40% EtOAc/hexanes) to give 0.975 g of the desired product. MS (M+H) 442.1.
