Procedure

To a solution of 3-bromo-5′-chloro-2′-fluoro-N-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridin-6-amine (100 mg, 0.250 mmol) in DMSO (1 mL) was added trans-1,4-diaminocyclohexane (114 mg, 0.998 mmol). The mixture was stirred at 110° C. for 19 hr. The crude reaction mixture was purified by reverse phase HPLC and lyophilized to give 51 mg of N2′-(trans-4-aminocyclohexyl)-3-bromo-5′-chloro-N6-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridine-2′,6-diamine as its TFA salt. LCMS (m/z): 494.2/496.1 (MH+), retention time=0.61 min; 1H NMR (400 MHz, DMSO-d6) d ppm 1.06-1.31 (m, 4 H) 1.31-1.49 (m, 2 H) 1.49-1.64 (m, 2 H) 1.64-1.82 (m, 1 H) 1.85-2.11 (m, 4 H) 2.93-3.12 (m, 3 H) 3.22 (t, J=10.96 Hz, 2 H) 3.61 (t, J=10.76 Hz, 1H) 3.81 (dd, J=11.35, 2.74 Hz, 2 H) 6.39 (s, 1 H) 6.48 (d, 1 H) 6.82 (br. s., 1 H) 6.94 (br. s., 1 H) 7.59 (d, J=9.00 Hz, 1 H) 7.78 (d, J=3.91 Hz, 2 H) 8.02 (s, 1H)
