Procedure

To a solution of 5-(methoxycarbonyl)picolinic acid (70.7 mg, 0.390 mmol) and DIPEA (0.20 mL, 1.148 mmol) in DMF (2 mL) were added HATU (223 mg, 0.586 mmol) and (S)-(4-(trifluoromethyl)phenyl)(3-(trifluoromethyl)pyridin-2-yl)-methanamine hydrochloride (Intermediate 1) (125 mg, 0.390 mmol). The resulting mixture was stirred at rt 16 h. The mixture was then diluted with THF (10 mL), MeOH (3 mL), and 1M LiOH (2 mL). After a further 16 h, the reaction was concentrated in vacuo, taken up in a minimum of DMF and purified by reverse-phase preparative HPLC (Shimadzu) on a Phenomenex Gemini™ column (5 micron, C18, 110 Å, Axia, 100×30 mm) eluting at 45 mL/min with a linear gradient of 20% to 90% MeCN (0.1% TFA) in H2O (0.1% TFA) over 10 minutes to give the title compound as a white solid after lypholization. 1H NMR (CDCl3, 300 MHz) δ ppm 9.74 (d, J=8.2 Hz, 1H), 9.25 (s, 1H), 8.97 (d, J=4.0 Hz, 1H), 8.47 (dd, J=8.0, 2.1 Hz, 1H), 8.26 (d, J=8.8 Hz, 1H), 8.04 (d, J=8.0 Hz, 1H), 7.61 (d, J=8.5 Hz, 2H), 7.55 (d, J=8.5 Hz, 2H), 7.46 (dd, J=7.5, 5.0 Hz, 1H), 6.88 (d, J=8.2 Hz, 1H). MS (ESI pos. ion) m/z: 469.9 (M+H).
