Reaction Steps

To a solution of tert-butyl 3,5′-dichloro-2′-fluoro-2,4′-bipyridin-6-yl((2,2-dimethyltetrahydro-2H-pyran-4-yl)methyl)carbamate (40 mg, 0.083 mmol) in DMSO (0.4 mL) was added trans-1,4-diaminocyclohexane (47 mg, 0.41 mmol) and DIEA (0.029 mL, 0.17 mmol). The mixture was stirred at 120° C. for 2 hr. The cooled reaction mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed sequentially with water and brine, dried over sodium sulfate, filtered, and concentrated. The resulting residue was re-dissolved in trifluoroacetic acid (1 mL), stirred for 15 min at ambient temperature, and then concentrated under reduced pressure. The resulting residue was taken up in DCM, washed with saturated aqueous sodium bicarbonate, dried (Na2SO4), filtered, and concentrated to give 39 mg of NT-(trans-4-aminocyclohexyl)-3,5′-dichloro-N6-((2,2-dimethyltetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridine-2′,6-diamine. LCMS (m/z): 478.4 (MH+), retention time=0.64 min.
