Reaction Steps

Methyl 3-(6-(3-methyl-1-(4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenyl)butylamino)nicotinamido)propanoate (50 mg, 0.099 mmol) was dissolved in water (5 mL) and tetrahydrofuran (5 mL). Lithium hydroxide (0.387 mL, 2N in water, 0.774 mmol) was added. The mixture was stirred at room temperature for 2 hours. 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. Purification by HPLC (column: Boston Analytics Symmetrix ODS-H 150×30 mm, 5 μm; modifier: formic acid 0.225%; gradient: 10 to 80% acetonitrile in water) gave (+/−)-3-(6-(3-methyl-1-(4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenyl)butylamino)nicotinamido)propanoic acid (25 mg, 52%). 1H NMR (400 MHz, CD3OD, δ): 8.70 (s, 1H), 8.40 (s, 1H), 7.97 (s, 1H), 7.82 (d, 1H), 7.74 (d, 2H), 7.53 (d, 2H), 6.59 (d, 1H), 5.12-5.02 (m, 1H), 3.57 (m, 2H), 2.59 (m, 2H), 1.89-1.69 (m, 2H), 1.68-1.58 (m, 1H), 1.02 (d, 3H), 0.98 (d, 3H). MS (M+1): 490.5.
