Procedure

Into a 50-mL round-bottom flask, was placed a solution of methyl 3-((2-(4-((3-(trifluoromethyl)benzyl)carbamoyl)pyridin-2-yl)-4-(piperidin-1-yl)phenyl)carbamoyl)benzoate (360 mg, 0.58 mmol, 1.00 equiv) in tetrahydrofuran/water (2:3) (35 mL), and lithium hydroxide hydrate (251.2 mg, 5.98 mmol, 10.25 equiv). The resulting solution was stirred overnight at 25° C. in an oil bath. The reaction progress was monitored by LCMS. The resulting mixture was concentrated under vacuum. The resulting solution was diluted with 50 mL of water adjusted to pH 2-3 with hydrogen chloride (2 mol/L). The resulting solution was extracted with 3×50 mL of ethyl acetate and the organic layers combined. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted in 325 mg (92%) of 3-((2-(4-((3-(trifluoromethyl)benzyl)carbamoyl)pyridin-2-yl)-4-(piperidin-1-yl)phenyl)carbamoyl)-benzoic acid as a yellow oil.
