To 3,5′-dichloro-2′-fluoro-N-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridin-6-amine (Intermediate G) (250 mg, 0.702 mmol) was added DMSO (3 ml) and trans-cyclohexane-1,4-diamine (952 mg, 6.32 mmol). The reaction mixture was stirred at 100° C. for 20 hours and the reaction progress was followed by LCMS. The reaction mixture was cooled, diluted with 250 ml ethyl acetate, washed with saturated sodium bicarbonate (1×), water (3×) and concentrated to constant mass, giving 320 mg of product as a free base, which was used without further purification. A portion of the title compound, 25 mg was purified by prep LC and lyapholized to give 17.6 mg of the title compound as a TFA salt. LCMS (m/z): 450.2 (MH+), retention time=0.58 min.; 1H NMR (300 MHz, METHANOL-d4, 25° C.) δ ppm 1.16-1.76 (m, 8H) 1.76-1.98 (m, 1H) 2.04-2.27 (m, 4H) 3.06-3.16 (m, 1H) 3.19 (d, J=6.74 Hz, 2H) 3.37 (t, J=11.87 Hz, 2H) 3.62-3.77 (m, 1H) 3.92 (dd, J=11.28, 3.08 Hz, 2H) 6.61 (d, J=8.79 Hz, 1H) 6.73 (s, 1H) 7.50 (d, J=9.08 Hz, 1H) 8.04 (s, 1H).
