Reaction Steps

A 20 drams vial was charged with methyl (±)-3-(4-(2,2-dimethyl-1-((6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridin-3-yl)amino)propyl)benzamido)propanoate (92 mg, 0.18 mmol), THF (1.8 mL) and MeOH (1.8 mL). NaOH 1M aq. (0.9 mL) was then added in one portion and the resulting mixture stirred for 30 minutes at room temperature. Organic solvents removed under reduced pressure and 5 mL of water added to the vial. Under magnetic stirring, citric acid solution (10%, aq.) added dropwise to reach ca. pH 3. The solid formed was recovered with a büchner funnel, washed with water and dried under high vacuum to provide (±)-3-(4-(2,2-dimethyl-1-((6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridin-3-yl)amino)propyl)benzamido)propanoic acid as a white solid (76.9 mg, 86.0%). 1H NMR (400 MHz, DMSO-d6) δ 0.98 (s, 9H) 2.44-2.48 (m, 2H) 3.38-3.47 (m, 2H) 4.33 (d, J=8.22 Hz, 1H) 6.54 (d, J=8.41 Hz, 1H) 7.17 (dd, J=8.90, 2.84 Hz, 1H) 7.44 (d, J=8.22 Hz, 2H) 7.55 (d, J=9.00 Hz, 1H) 7.74 (d, J=8.41 Hz, 2H) 7.84 (d, J=2.54 Hz, 1H) 8.08 (s, 1H) 8.44 (t, J=5.28 Hz, 1H) 8.84 (s, 1H) 12.18 (br. s., 1H); MS (M+1): 490.4.
