Procedure

To a stirred solution of (3R)-1-[trans-2-(benzyloxy)cyclohexyl]pyrrolidin-3-amine 2 HCl salt (0.14 g, 0.45 mmol) and (3-trifluoromethyl-benzoylamino)-acetic acid (0.111 g, 0.45 mmol) in CH2Cl2 (5 mL) was added Et3N (0.188 mL, 1.35 mmol) followed by EDC (0.0863 g, 0.45 mmol) and HOBt (0.069 g, 0.45 mmol). The mixture was stirred at room temperature overnight. Then the reaction mixture was diluted with EtOAc and washed with saturated Na2CO3 and brine. The organic layers was dried (MgSO4), concentrated and flash chromatographed (EtOAc to 10% MeOH/EtOAc) to give 0.186 g of the title compound. MS (EI) calcd: M+1=504.2; found: 504.4.
