Versuchsvorschrift

(+\)-3-(4-(cyclohexyl(6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridine-3-ylamino)methyl)benzamido)propanoic acid (Example 101) was resolved by SFC (Column: Chiralpak AD-H 25×4.6 mm; mobile phase: 25% ethanol in CO2; modifier: 0.2% isopropylamine; flow rate: 2.5 mL/min) to provide 3-(4-(cyclohexyl(6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridine-3-ylamino)methyl)benzamido)propanoic acid, Isomer 1 (retention time: 6.93 min) and 3-(4-(cyclohexyl(6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridine-3-ylamino)methyl)benzamido)propanoic acid, Isomer 2 (retention time: 9.58 min) as their isopropylammonium salts. The salts were dissolved in water and the pH adjusted to 3.5 by addition of 1N aqueous HCl. The mixtures were extracted with dichloromethane. The organic layers were dried over MgSO4 and concentrated to provide 3-(4-(cyclohexyl(6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridine-3-ylamino)methyl)benzamido)propanoic acid, Isomer 1 and 3-(4-(cyclohexyl(6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridine-3-ylamino)methyl)benzamido)propanoic acid, Isomer 2. Spectral data for Isomer 1: 1H NMR (400 MHz, CDCl3) δ 8.58 (s, 1H), 7.77 (s, 1H), 7.65-7.72 (m, 3H), 7.60 (d, J=8.8 Hz), 7.32 (d, J=8.2 Hz, 2H), 6.82-6.88 (m, 1H), 6.71-6.78 (m, 1H), 4.15 (d, J=6.2 Hz, 1H), 3.65-3.73 (m, 2H), 2.63-2.73 (m, 2H), 1.83-1.93 (m, 1H), 1.59-1.82 (m, 4H), 1.46-1.56 (m, 1H), 0.94-1.28 (m, 6H). MS (M+H)=516.2.
