3-chloro-2′,5′-difluoro-N-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridin-6-amine (0.0509 g, 0.150 mmol) was dissolved in anhydrous DMSO (3.0 ml) and charged to a microwave vial. This was treated with trans-cyclohexane-1,4-diamine (0.171 g, 1.498 mmol). The reaction mixture was then heated at 100° C. for 18 hr. More trans-cyclohexane-1,4-diamine (0.171 g, 1.498 mmol) was added and the reaction mixture was stirred at 120° C. for 18 hr. The reaction mixture was allowed to cool to ambient temperature. The material was purified by preparative reverse-phase HPLC to give 0.2410 g (30%) of N2′-(trans-4-aminocyclohexyl)-3-chloro-5′-fluoro-N6-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridine-2′,6-diamine as the TFA salt. LCMS (m/z): 434.2 (MH+), retention time=0.55 min.
