1-Amino-2-phenylpentan-2-ol (0.099 g, 0.45 mmol, 1.5 eq) was dissolved in NMP (3 mL) and to this solution was added 3-fluoro-4-(2-(pyridin-2-ylamino)thiazol-5-ylthio)picolinic acid (0.101 g, 0.30 mmol), EDAC (0.089 g, 0.45 mmol, 1.5 eq), HOBt (0.042 g, 0.30 mmol, 1 eq) and diisopropylethylamine (0.16 mL, 0903 mmol, 3 eq). The resulting mixture was stirred at 23° C. for 2 h. The mixture was then purified on preparative HPLC (ammonium acetate/water/acetonitrile) and freeze dried to give the title compound (0.0552 g, 36%). 1H NMR (400 MHz, DMSO-d6) δ ppm: 0.76 (3H, t, J=7.33 Hz), 0.84-0.96 (1H, m), 1.19-1.30 (1H, m), 1.68-1.79 (2H, m), 3.63 (2H, d, J=5.81 Hz), 5.29 (1H, s), 7.01 (1H, dd, J=6.82 and 5.56 Hz), 7.05 (1H, t, J=5.18 Hz), 7.12 (1H, d, J=8.34 Hz), 7.20 (1H, t, J=7.33 Hz), 7.31 (2H, t, J=7.71 Hz), 7.42-7.46 (2H, m), 7.78 (1H, td, J=7.77 and 1.89 Hz), 7.82 (1H, s), 8.22-8.26 (2H, m), 8.31 (1H, dd, J=5.05 and 1.01 Hz), 11.88 (1H, s). LC/MS (M+H)+: 510. HPLC ret. time (Condition J): 6.095 min. HRMS calcd: 510.1434; found: 510.1412.
