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.
