Reaction Steps

Combine 1-(2-methyl-4′-trifluoromethyl-biphenyl-4-yl)-heptan-1-ol (0.090 g, 0.25 mmol) and 3-(3-fluoro-4-hydroxy-benzoylamino)-propionic acid ethyl ester (0.050 g, 0.20 mmol) in toluene (1.0 mL). Add 1,1′(diazocarbonyl)dipiperidine (0.076 g, 0.3 mmol) followed by tributyl-phosphane (0.074 mL, 0.3 mmol) under inert atmosphere. Stir at room temperature for 16 hours. Dilute reaction with ethyl acetate filter and remove solvent under reduced pressure. Purify on silica gel chromatography (0-50% Ethyl acetate/hexanes gradient) to provide 0.105 g of title compound (90%).
