Procedure

Combine 1-(4′-trifluoromethyl-biphenyl-4-yl)-heptan-1-ol (0.257 g, 0.76 mmol) and 3-(3-Fluoro-4-hydroxy-benzoylamino)-propionic acid ethyl ester (0.150 g, 0.59 mmol) in toluene (3.0 mL). Add 1,1′(diazocarbonyl)dipiperidine (0.223 g, 0.88 mmol) followed by tributyl-phosphane (0.22 mL, 0.88 mmol) under inert atmosphere. Stir at room temperature for 18 hours. Dilute reaction with ethyl acetate filter and remove solvent under reduced pressure. Purify on silica gel chromatography (0-70% Ethyl acetate/hexanes gradient) to provide 0.305 g of title compound (90%).
