Versuchsvorschrift

To a solution of 5-(methoxycarbonyl)picolinic acid (101 mg, 0.558 mmol) in DCM (4 mL) was added HATU (217 mg, 0.571 mmol) and DIPEA (0.20 mL, 1.148 mmol). After stirring for 30 min at rt, the reaction was treated with (S)-(3-fluoropyridin-2-yl)(4-(trifluoromethyl)phenyl)methanamine hydrochloride (Intermediate 2) (125 mg, 0.364 mmol). After 16 h, the reaction was concentrated in vacuo and then taken up in THF (3 mL), MeOH (1 mL), and 1M LiOH (1 mL). The resulting mixture was stirred at rt for 2 h. The reaction mixture was concentrated in vacuo, acidified with 1N HCl and extracted with EtOAc (3×5 mL). The combined EtOAc layers were concentrated in vacuo and chromatographed through a Redi-Sep® pre-packed silica gel column (4 g), eluting with 0% to 100% EtOAc in hexane, to provide the title compound as an off-white solid. 1H NMR (CDCl3:CD3OD, 300 MHz) δ ppm 9.21 (d, J=1.5 Hz, 1H), 8.47 (d, J=4.7 Hz, 1H), 8.39 (dd, J=8.0, 1.9 Hz, 1H), 8.14 (d, J=8.0 Hz, 1H), 7.56 (d, J=8.5 Hz, 2H), 7.50 (d, J=8.6 Hz, 2H), 7.42 (t, J=9.5 Hz, 1H), 7.27-7.32 (m, 1H), 6.63 (s, 1H).
