Versuchsvorschrift

To 5′-chloro-2′-fluoro-6-(3-fluorobenzyloxy)-2,4′-bipyridine (30 mg, 0.090 mmol) was added DMSO (0.8 ml), TEA (0.025 ml, 0.180 mmol), and tert-butyl (trans-4-aminocyclohexyl)methylcarbamate (41.2 mg, 0.180 mmol). The reaction mixture was flushed with argon and stirred at 100-105° C. for 40 hr. Formation of the intermediate product tert-butyl(trans-4-(5′-chloro-6-(3-fluorobenzyloxy)-2,4′-bipyridin-2′-yl-amino)cyclohexyl)methylcarbamate was indicated by LCMS. (LCMS (m/z): 541.4 (MH+), retention time=1.05 min.). The solvent DMSO was removed under reduce pressure. The Boc group was removed from the intermediate by adding 4M HCl in Dioxane (1.5 ml, 6.00 mmol), followed with stirring at ambient temperature for 90 minutes. The solvent was removed under reduced pressure. The crude product was dissolved in 1.0 ml of DMSO with 0.075 ml of water, filtered and purified by prep LC. After lyphilization, 28.3 mg of the title compound was obtained as a TFA salt. LCMS (m/z): 441.3 (MH+), retention time=0.76 min.; 1H NMR (300 MHz, METHANOL-d4, 25° C.) δ ppm 1.12-1.29 (m, 2H) 1.29-1.47 (m, 2H) 1.60-1.76 (m, J=14.76, 7.51, 3.66, 3.66 Hz, 1H) 1.92 (d, J=12.60 Hz, 2H) 2.16 (d, J=10.55 Hz, 2H) 2.84 (d, J=6.74 Hz, 2H) 3.58-3.71 (m, 1H) 5.43 (s, 2H) 6.92-6.99 (m, 2H) 6.99-7.08 (m, 1H) 7.18 (d, J=9.67 Hz, 1H) 7.25 (d, J=7.62 Hz, 1H) 7.30-7.42 (m, 2H) 7.83 (t, J=7.77 Hz, 1H) 8.01 (s, 1H)
