Procedure

To a mixture of N2′-(trans-4-aminocyclohexyl)-3-bromo-5′-chloro-N6-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridine-2′,6-diamine (30 mg, 0.061 mmol) and sodium carbonate (19 mg, 0.18 mmol) in DMSO (0.6 ml) was added p-toluenesulfonic acid 2-methoxyethyl ester (21 mg, 0.091 mmol). The mixture was stirred at 85° C. for 20 hr in a sealed microwave vial. The cooled reaction mixture was filtered. The filtrate was concentrated and the resulting residue was purified by reverse phase HPLC and lyophilized to give 3.8 mg of 3-bromo-5′-chloro-N2′-(trans-4-(2-methoxyethylamino)cyclohexyl)-N6-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridine-2′,6-diamine as its TFA salt. LCMS (m/z): 554.1 (MH+), retention time=0.61 min.
