To a solution of (+/−)-methyl 6-(3-methyl-1-(4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenyl)butylamino)nicotinate (30 mg, 0.069 mmol) in tetrahydrofuran (3 mL) was added lithium hydroxide (0.103 mL, 2N in water, 0.207 mmol). The mixture was stirred at 50° C. overnight. The mixture was neutralized with 1N aqueous hydrochloric acid and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered and concentrated to give 6-(3-methyl-1-(4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenyl)butylamino)nicotinic acid (25 mg, 87%) as a white solid. MS (M+1): 419.1.
