Procedure

To a solution of (S)-5-bromo-N-((4-(trifluoromethyl)phenyl)(3-(trifluoro-methyl)pyridin-2-yl)methyl)picolinamide (Example 205) (0.100 g, 0.198 mmol) in DMF (1.3 mL) was added zinc cyanide (0.050 mL, 0.793 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.023 g, 0.020 mmol). The resulting mixture was subjected to a microwave irradiation at 140° C. for 20 min. The mixture was then purified by preparative HPLC (0%-100% MeCN 0.1% TFA/H2O 0.1% TFA) to give the title compound as a white solid. 1H NMR (400 MHz, MeOH) δ ppm 8.95-9.06 (m, 2H), 8.39 (dd, J=8.1, 2.1 Hz, 1H), 8.21-8.32 (m, 2H), 7.57-7.70 (m, 5H), 6.89 (s, 1H). MS (ESI pos. ion) m/z: 451.1 (M+H).
