Procedure

Methyl 3-(6-(4,4,4-trifluoro-1-(4′-(trifluoromethyl)biphenyl-4-yl)butylamino) nicotinamido)propanoate (13 mg, 0.023 mmol) was dissolved in 1 mL methanol. 100 μL 1N aqueous sodium hydroxide was added. The resulting solution was stirred at room temperature overnight. The reaction solution was concentrated under reduced pressure. The residue was dissolved in 5 mL water and the solution adjusted to pH 3 by addition of 1N aqueous HCl. The resulting mixture was extracted with ethyl acetate. The organic extract was dried over MgSO4 and concentrated to give a colorless film. Residual solvent was removed under a stream of nitrogen to give 3-(6-(4,4,4-trifluoro-1-(4′-(trifluoromethyl)biphenyl-4-yl)butylamino)nicotinamido)propanoic acid (7.6 mg, 64%) as a colorless solid. 1H NMR (400 MHz, CDCl3) δ 9.24 (br s, 1H), 8.06-8.14 (m, 2H), 7.55-7.65 (m, 4H), 7.52 (d, J=8.2 Hz, 2H), 7.38 (d, J=8.2 Hz, 2H). 6.40 (d, J=9.8 Hz, 1H), 4.46-4.55 (m, 1H), 3.64-3.72 (m, 2H), 2.52-2.59 (m, 2H), 2.04-2.32 (m, 4H).
