Participants

Reaction Steps

Methyl 3-(4-(1-(6-(4-phenyl-1H-pyrazol-1-yl)pyridine-3-ylamino)butyl)benzamido)propanoate (82.1 mg, 0.165 mmol) was dissolved in methanol (0.5 mL) and tetrahydrofuran (0.5 mL). 1N Sodium hydroxide (0.33 mL) was added and the reaction was stirred at room temperature for 24 hours. The reaction was then concentrated. The crude residue was taken up in water and acidified with 1N hydrochloric acid to pH=3. A white precipitate formed. The solids were filtered off and dried under vacuum to give (+/−)-3-(4-(1-(6-(4-phenyl-1H-pyrazol-1-yl)pyridine-3-ylamino)butyl)benzamido)propanoic acid (61.6 mg, 77%) as an off-white solid. 1H NMR (400 MHz, CD3OD, δ): 8.57 (d, J=1.0 Hz, 1H), 7.96 (d, J=0.8 Hz, 1H), 7.78-7.69 (m, 3H), 7.61-7.50 (m, 3H), 7.47 (d, J=8.4 Hz, 2H), 7.38-7.31 (m, 2H), 7.24-7.16 (m, 1H), 7.05 (dd, J=8.9, 3.0 Hz, 1H), 4.48-4.41 (m, 1H), 3.63-3.55 (m, 2H), 2.60 (t, J=6.9 Hz, 2H), 1.94-1.69 (m, 2H), 1.58-1.33 (m, 2H), 0.96 (t, J=7.4 Hz, 3H). MS (M+1): 484.4.
