Mix 3′,5′-dichloro-4′-[(R)-trans-1-(4-methoxy-cyclohexyl)-2-oxo-pyrrolidin-3-ylmethyl]-biphenyl-4-carboxylic acid (0.350 g, 0.74 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.216 g, 1.11 mmol), N-methylmorpholine (0.33 mL, 2.95 mmol), hydroxybenzotriazole (0.247 g, 0.74 mmol) and 4-trifluoromethyl-piperidine hydrochloride (0.226 g, 1.47 mmol) in CH2Cl2 (10 mL). Stir for 12 hours at room temperature. Quench with 1N HCl and extract with ethyl acetate. Wash the extract with saturated aqueous sodium bicarbonate brine. Dry over magnesium sulfate, filter, and concentrate under vacuum. Purify by flash column chromatography to recover 0.350 g (78%) of the title compound: MS (m/z): 611 (M+).
