3-(4-{4,4-Dimethyl-1-[6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-pentyloxy}-benzoylamino)-butyric acid methyl ester are taken into THF (1.0 mL) and treated with NaOH (1.0 mL, 5.0 N), then refluxed under nitrogen. The reaction mixture is neutralized with HCl (1.0 mL, 5.0 N), extracted with ethyl ether, dried over sodium sulfate. Concentration gives the title compound, (163 mg, 0.15 mmol) 72% 2 steps. MS (ES): 541.3 [M+H]−, the structure is also confirmed by proton NMR.
