Procedure

To a flask containing 3-(4-((3,3-difluorocyclobutyl)(6-(4-(trifluoromethyl)-1H-imidazol-1-yl)pyridin-3-ylamino)methyl)benzamido)propanoate (7.00 mg, 0.0100 mmol) was added water (0.0650 mL), tetrahydrofuran (0.0650 mL), and methanol (0.0650 mL). Lithium hydroxide monohydrate (27.3 mg, 0.650 mmol) was then added. The suspension was stirred at room temperature for 2 hours. The reaction was quenched with 1 N hydrochloric acid to pH 3 and extracted three times with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered, and concentrated to give (+/−)-3-(4-((3,3-difluorocyclobutyl)(6-(4-(trifluoromethyl)-1H-imidazol-1-yl)pyridin-3-ylamino)methyl)benzamido)propanoic acid (4.5 mg, 70%) of a glass-like material. 1H NMR (400 MHz, CDCl3) δ 8.36-8.34 (m, 1H), 8.16-8.12 (m, 1H), 7.86 (d, J=2.9 Hz, 1H), 7.84-7.77 (m, 2H), 7.58-7.51 (m, 2H), 7.39 (dd, J=8.8, 0.6 Hz, 1H), 7.10 (dd, J=8.8, 2.9 Hz, 1H), 4.48 (d, J=8.8 Hz, 1H), 3.63 (t, J=6.9 Hz, 2H), 2.94-2.73 (m, 1H), 2.64 (t, J=6.9 Hz, 2H), 2.61-2.49 (m, 2H), 2.49-2.33 (m, 2H). MS (M+1): 524.3.
