The mixture of 1-benzyl-4-(3,5-bis-trifluoromethyl-benzylamino)-pyrrolidine-2-carboxylic acid (65 mg, 0.146 mmol), 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (54.5.0 mg, 0.292 mmol), N-hydroxybenzotriazole (20.7 mg, 0.146 mmol), and 1-(3-trifluoromethyl-phenyl)-piperazine (29.67 mg, 0.219 mmol), triethylamine (0.08 ml) in dry dichloromethane (2 mL) was stirred overnight, and then concentrated. The residue was purified by preparative HPLC on reversed phase eluting with an acetonitrile/water [0.1% aq NH3 (25%)] gradient to afford the title compound (10.2 mg, 10.6%) as a light yellow oil. MS m/e=659.4 [M+H]+.
